C. Rectangle
D. Trapezoid
E. Rhombus
F. Square
Answer:
it is a trapezoid and a quadrilateral
Explaination -
Square is a quadrilateral of 4 equal side and 4 equal angles so it is not square as all sides are unequal and all angles are also unequal
rhombus is a quadrilateral which has equal sides 4 equal angles and it's diagonal bisects each other.
rectangle has two opposite sides equal and parallel and each Ange equal as 90°
parallelogram is a quadrilateral in which a pair of opposite sides are parallel and equal and the remaining sides are unequal
Solve the following inequality |x| < 13
Answer:
x < 13 and x > -13
Step-by-step explanation:
Split the absolute value equation into 2 equations to account for the positive and negative answers possible with absolute values.
Write the positive value first by removing the absolute value symbol.
x < 13
Flip the inequality and make the 13 negative for the other side.

Two sets of values are given below.
set 1: 29 , 31 , 27 , 33 , 30
set 2: 33 , 31 , 26 , 31 , 29
Which of the following conclusions can be drawn about the means of these two sets?
A. The mean for set 2 is equal to the mean for set 1.
B. The medians of both sets are equal to the means of both sets.
C. The mean for set 2 is lower than the mean for set 1.
D. The mean for set 2 is higher than the mean for set 1.
The correct option is the mean for set 2 is equal to the mean for set 1. (option A).
What is the true option?
Mean is a measure of central tendency that is used to determine the average of a set of numbers.
Mean = sum of the numbers / total number
Mean of set 1 = (29 + 31 + 27 + 33 + 30) / 5
= 150 / 5 = 30
Mean of set 1 = (33 + 31 + 26 + 31 + 29) / 5
= 150 / 5 = 30
Median is the measure of center of a dataset. It determines the value that is at the center of a dataset that is arranged in either ascending or descending order.
Set 1 arranged in ascending order : 27, 29, 30, 31, 33
Median of set 1 = 30
Set 2 arranged in ascending order : 26, 29, 31, 31, 33
Median of set 2 = 31
Differnce in the median = 31 - 30 = 1

if the ratio of the sides of a triangle are 13:14:15 and its perimeter is 84 cm, find the area of the triangle.
Answer:
The ratio of sides of triangle = 13:14:15
perimeter = 84 CM
perimeter of a triangle = Sum of all sides
let the sides of a triangle be 13x, 14x and 15x
84 = 13x + 14x + 15x
84 = 42x
x = 2
13x = 13* 2 = 26 CM
14x = 14*2 = 28 CM
15x = 15*2 = 30 CM
Carolyn bought two brands of socks. She bought a total of 5 pairs. One brand cost $2 each and the other brand cost $3 each. She spent $13. Find the number of pairs each brand of socks she bought
Answer:
Step-by-step explanation:
Declaration
Let Brand A number of 2.00 socks= x
Let Brand B number of 3.00 socks = y
Equations
Number of socks : x + y = 5
Cost of socks: 2x + 3y = 13
Solution
Multiply top equation by 2
2(x+ y = 5)
2x + 2y = 10
Write the new equation under the cost of socks equation
2x + 3y = 13
2x + 2y = 10 Subtract.
y = 3
She spent 3 dollars on 1 pair of socks.
Now she needs to calculate the number of 2.00 dollar socks
2x + 3y = 13
2x + 3*3 = 13 Combine the left
2x + 9 = 13 Subtract 9 from both sides.
2x +9-9 = 13-9 Combine
2x = 4 Divide by 2
2x/2 = 4/2
x = 2
Answer
#2 dollar socks = 2
#3 dollar socks = 3

Select the correct answer. Simplify the polynomial expression. 3x(-2x+7) -5(x-1)(4x-3)
Answer:
The simplified form is -26x^2 + 56x -15
Step-by-step explanation:
We need to solve the expression:
3x(-2x+7)-5(x-1)(4x-3)
Multiplying the terms outside the bracket with the terms inside the bracket.
=-6x^2+21x-5(x(4x-3) -1(4x-3))
= -6x^2+21x-5(4x^2-3x-4x+3)
= -6x^2+21x-5(4x^2-7x+3)
Now multiply -5 with the terms inside the bracket
= -6x^2+21x -20x^2 +35x -15
Now, Combining the like terms:
= -6x^2 -20x^2 +21x+35x -15
Adding the like terms
= -26x^2 + 56x -15
So, the simplified form is -26x^2 + 56x -15
-26^2+56x-15 yea that should be the answer

In triangles APD and BPC; DP = PC Sides of equilateral triangle DPC are equal
In triangles APD and BPC; AD = BC Sides of square ABCD are equal
In triangles APD and BPC; angle ADP = angle BCP Angle ADC = angle BCD = 90° so angle ADP = angle BCP = 60°
Triangles APD and BPC are congruent SAS postulate
What is the error in Ted's proof? (1 point)
He writes the measure of angles ADP and BCP as 60° instead of 45°.
He uses the SAS postulate instead of AAS postulate to prove the triangles congruent.
He writes the measure of angles ADP and BCP as 60° instead of 30°.

1 peasant changed rabbits to hens and 2 rabbits were equal to 3 hens, each hen produced the eggs that were equal to ⅓ of the total number of hens, the peasant sold the eggs, 9 eggs will cost as many pennies as each hen that produced the eggs and totally he got 72 pennies so how many hens and how many rabbits he had?
The peasant had 28 hens and 42 rabbits
How to determine the number of hens and rabbits?Represent hens with h, eggs with e and rabbits with r.
So, we have:
2r = 3h
e = 1/3h
Make h the subject in e = 1/3h
h = 3e
He got 72 pennies.
So, we have:
r + h = 72
Multiply through by 2
2r + 2h = 144
Substitute 2r = 3h in 2r + 2h = 144
3h + 2h = 144
Evaluate the sum
5h = 144
Divide by 5
h = 28.8
Remove decimal
h = 28
Recall that:
2r = 3h
So, we have:
2r= 3 * 28
Divide by 2
r = 3 * 14
Evaluate the product
r = 42
Hence, the peasant had 28 hens and 42 rabbits

In the system of equations, a and b are constants. if the system has infinitely many solutions, what's the value of ab?
Answer:
The system has infinitely many solutions when a = 3/4 and b = 1/2Given
System of linear equations
ax +by = 163x+2y=64To find Values of a and b that leads to infinitely many solutionsSolutionThe linear system of equations has infinitely many solutions when lines overlap, so both have same slope and y-intercept.
We can solve it in two different ways
1. Note that when the first equation is multiplied by 4, it has same value of constant as the second equation, which is 64.
4ax + 4by = 643x + 2y = 64When compared it gives us:
4a = 3 ⇒ a = 3/44b = 2 ⇒ b = 2/4 = 1/22. Convert both equations from standard to slope-intercept form and compare:
ax + by = 16by = -ax + 16y = - (a/b)x + 16/b3x + 2y = 642y = - 3x + 64y = - (3/2)x + 32Work out values of a and b:
16/b = 32 ⇒ b = 16/32 ⇒ b = 1/2- (a/b) = - 3/2 ⇒ a/b = 3/2 ⇒ a = 3b/2 ⇒ a = 3(1/2)/2 ⇒ a = 3/4Using circle P with a radius of 7 cm, find the EXACT

There are 8 kids at a birthday party. If there are 6 girls and 2 boys at a party what fraction of the kids are girls?
Okay, so out of 8 kids, we know that 6/8 are girls and 2/8 are boys. Its asking us what fraction of the kids are girls. The denominator (the bottom part of the fraction will be the amount of kids at the party, 8) and the top part, the numerator, will be 6 as there are 6 girls at the party of the 8 attendees.
So the fraction is 6/8. However we can reduce this by dividing both sides of the fraction by a common factor, 2!
So your final answer is 3/4.
