A perfect square trinomial is a trinomial that factors as two identical binomials.
For example, x² + 8x + 16 factors as (x + 4)(x + 4) or (x + 4)².
Another example would be x² - 12x - 36 which factors as (x - 6)².

In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C.
Answer:
The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.
Step-by-step explanation:

Answer:
Sample response: The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.

Solving the Simplified Equation
Fill in the blanks to complete the description of
how to solve the equation
28x - 56 = 22x - 65.
First, get the variable on the left-hand side of the
equation by subtracting 22x from both sides to get
bx - 56 = -65. Next, use the
property of equality to isolate
the variable
DONE
Answer:
- 1.5
Step-by-step explanation:
put two x variables in one place and two numbers in one place
28x- 22x = 56-65
6x = -9
x=-1.5

Find the areas of the circle. Round your answers to two decimal places, if necessary.
Answer:
3.14 yd²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
Filling in the values, we find the area of this circle to be ...
A = 3.14×(1 yd)² = 3.14 yd²

Explanation:
Y is between X and Z (not necessarily at the midpoint). This means the three points are on the same line. Going from left to right we have X, Y and Z in that exact order.
Put another way, segment XZ is cut into smaller pieces XY and YZ.
The smaller pieces XY and YZ add back up to the largest segment XZ.
--------------
XY + YZ = XZ
( XY ) + ( YZ ) = XZ
( 7a ) + ( 5a ) = 6a+24 ..... substitution
7a+5a = 6a+24
12a = 6a+24
12a-6a = 24 ....... subtracting 6a from both sides
6a = 24
a = 24/6 ....... dividing both sides by 6
a = 4 is the first answer we're after
-------------
Use this value of 'a' to find the length of each segment
XY = 7a = 7*4 = 28
YZ = 5a = 5*4 = 20 is the second answer we want
XZ = 6a+24 = 6*4+24 = 48
Note how XY+YZ = 28+20 = 48 to match with XZ = 48 we got in the previous line above.

Write a conjecture that describes the pattern in each sequence. Then use your conjecture to find the next item in the sequence.
-5, 10, -20, 40,_,_,_
Answer:
The next 2 items would be -80 and 160
The complete series is -5, 10, -20, 40, -80, 160, -320 and this can be determined by using the geometric progression.
Given :
-5, 10, -20, 40,...
The following steps can be used in order to determine the next item in the sequence:
Step 1 - The given sequence is in the geometric progression.
Step 2 - Write the given series.
-5, 10, -20, 40,...
Step 3 - The next term in the given sequence is:
= - 40 [tex]\times[/tex] 2
= - 80
Step 4 - After the above term the term obtained is:
= [tex]80\times 2[/tex]
= 160
Step 5 - After the above term the term obtained is:
= [tex]-160\times 2[/tex]
= -320

What is 46% of 1000? Round to the nearest hundredth
Answer:
500
Step-by-step explanation:
I will tell you what 460 is rounded to the nearest hundred and also show you what rules I used to get to the answer.
We did not necessarily round up or down, but to the hundred that is nearest to 460.
500
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Triangle ABC has vertices (4,-1), B(5,6) and C(1,3). Prove using coordinate geometry that ABC is an isosceles right triangle.
Step-by-step explanation:
first find distance between ab
then between bc
then ac
in isosceles triangle 2 sides are equal
so if two sides means the distance we find are same
the givan triangle is isosceles
Answer:
the coordinates of vertices triangle ABC are (4,-1), B(5,6) and C (1,3) prove that triangle ABC is an isosceles right triangle.

Answer:
x = 5, RT = 18
Step-by-step explanation:
[tex]\triangle MNL \sim \triangle SRT... (given) \\
\therefore \frac{MN}{SR} = \frac{NL}{RT}.. (c.s.s.t)\\ \\
\therefore \frac{84}{24} = \frac{63}{3x+3}\\ \\
\therefore \frac{7}{2} = \frac{63}{3x+3}\\ \\
\therefore 3x+3 = \frac{63\times 2}{7}\\ \\
\therefore 3x + 3 = 9\times 2\\
\therefore 3x + 3 = 18\\
\therefore 3x = 18 - 3\\
\therefore 3x=15\\
\therefore x = \frac{15}{3}\\

Identify the graph shown as linear or non linear. Then estimate and interpret the intercepts of the graph, any symmetry, where the function is positive, negative, increasing, and decreasing, the x-coordinate of any relative extrema, and the behavior of the graph.
PLEASE HELP. Thank you. Due at 1:30
Answer:
see below
Step-by-step explanation:
Identify the graph shown as linear or non linear. - nonlinear since it is not a linear
Then estimate and interpret the intercepts of the graph,
y intercept - ( 0,-6) where it crosses the y axis
x intercepts ( -12,0) and ( 12,0)
any symmetry, symmetric across the y axis
where the function is positive, or above zero (-∞, -12) and (12,∞)
negative, or below zero ( -12,12)
increasing, growing ( 0, ∞)
and decreasing, getting smaller (-∞, 0)
the x-coordinate of any relative extrema, the minimum is (0,-6)
and the behavior of the graph. As x goes to -∞ y goes to ∞ and s x goes to ∞ y goes to ∞

1/5x + 4 =1/3x-8
Can you show your work too? That would be great
Answer:
90
Step-by-step explanation:
1/5x+4=1/3x-8
add 8 to both sides and subtract 1/5x from both sides
4+8=1/3x-1/5x
12=5/15x-3/15x
12=2/15x
divide both sides by 2/15
12÷2/15=x
when dividing by a fraction, invert and multiply
12*15/2=x
90=x
CHECK:
1/5(90)+4=1/3(90)-8
18+4=30-8
