Answers
Answer:
3x² + 9x + 6
Explanation:
(3x + 3)(x + 2)
= (3x + 3)(x + 2)
= (3x)(x) + (3x)(2) + (3)(x) + (3)(2)
= 3x² + 6x + 3x + 6

∠A and \angle B∠B are vertical angles. If m\angle A=(5x+5)^{\circ}∠A=(5x+5)
∘
and m\angle B=(4x+29)^{\circ}∠B=(4x+29)
∘
, then find the measure of \angle A∠A.
Answers
If A and B are vertical angles, then they are congruent, so their measures are equal.
This means
(5x + 5)º = (4x + 29)º
5x + 5 = 4x + 29
x = 24
Then angle A has measure (5*24 + 5)º = 125º.

Each of a regular polygon is 140°,find the number of the sides that ghe polygon has
Answers
Answer:
the answer should be 360/36=10 sides
Step-by-step explanation:
A regular polygon is 144 deg the exterior angle is 36 deg.
Answer:
9 sides
Step-by-step explanation:
Internal angles of the regular polygon have a property, sum of interior angles is equal to:
sum = (n-2)*180°n sides each interior angle equal to 140°, then
sum = 140°nComparing the two equations:
(n-2)*180= 140n180n - 360 = 140n40n = 360n = 360/40n = 9The polygon has 9 sides

the curved surface of a cylindrical surface is 704 cm square calculate the height when the radius is 8cm
Answers
Answer:
CSA of cylinder = 704cm²
We know that
CSA of cylinder = 2πrh

Answers
Answer:
4 hrs
Step-by-step explanation:
Let h be the number of hours spent teaching lessons
Then 8h is the amount earned from swimming lessons
Total amount earned = amount from swimming lessons + $20 registration fee
Total amount earned = $52
Therefore, 52=8h+20
32=8h

(a) An angle measures 64°. What is the measure of its complement?
(b) An angle measures 145º. What is the measure of its supplement?
Answers
Answer:
(a) 26 degrees
(b) 35 degrees
Step-by-step explanation:
(a) complementary angles add up to 90 degrees, therefore the complementary angle to 64 degrees would be 90 - 64, or 26 degrees.
(b) supplementary angles add up to 180 degrees, therefore the supplementary angle to 145 degrees would be 180 - 145, or 35 degrees.
What is the value of x in the equation 4x - 2(x + 3) = 8?
A x = 1
B. X = 2.5
C x = 3.5
D. x = 7
Answers
Answer:
x = 7
Step-by-step explanation:
The given equation is 4x - 2(x + 3) = 8. We need to find the value of x. The steps are as follows :
Firstly opening the bracket on the LHS,
4x -2x-6 = 8
Adding like terms together. So,
2x = 8+6
2x = 14
x = 7
So, the value of x is 7. Hence, the correct option is (d).

Find the exact sum of the arithmetic series
6+3.8+⋯−29.2
Answers
Answer:
-197.2
Step-by-step explanation:
Since it is arithmetic series, first find the difference d between the two know series.
3.8 - 6 = - 2.2
d = -2.2
a = 6
Tn = -29.2
Looking for the n term, use the linear method.
Tn = a+( n - 1)d
Substitute all the parameters
-29.2 = 6+( n - 1 ) -2.2
-29.2 = 6 - 2.2n + 2.2
- 29.2 = 8.2 - 2.2n
-29.2 - 8.2 = - 2.2n
-37.4 = -2.2n
n = 37.4/ 2.2
n = 17 terms.
To Find the exact sum of the arithmetic series, use the sum formula below
Sm = n/2( 2a + (n - 1)d)
Sm = 17/2( 2 × 6 + ( 17 - 1 ) -2.2
Sm = 17/2(12 - 35.2)
Sm = 8.5( - 23.2)
Sm = - 197.2
Therefore, the exact sum of the arithmetic series is -197.2

What is the value of x in the equation 0.3x = 12?
Answers
Answer:
You divide 0.3 by 12 if you don’t want a decimal do it the other way around the answer is x=40
Step-by-step explanation:
The value of x that satisfies the equation 0.3x = 12 is 40.
We have,
To find the value of x in the equation 0.3x = 12, we need to isolate x on one side of the equation.
We can do this by dividing both sides of the equation by 0.3, which will cancel out the coefficient of x on the left side:
(0.3x) / 0.3 = 12 / 0.3
Simplifying this equation gives:
x = 40
Thus,
The value of x that satisfies the equation 0.3x = 12 is 40.
