(9t-4)(-9t-4)
Multiply each term by each term then combine like terms:
9t x -9t = -81t^2
9t x -4 = -36t
-4 x -9t = 36t
-4 x -4 = 16
-81t^2 - 36t + 36t + 16
Combine like terms:

If PQR is an equilateral triangle, PQ=18x+1, QR=24x-17, and PR=15x+10, find x and the measure of each side.
Answer
QR= PQ= PR
18x+1= 24x-17
18x-24x= -17-1
-6x= -18
x= 3
QR= 24(3)-17= 55
PQ= 18(3)+1= 55
PR= 15(3)+10=55
Answer:
The value of x is 3. The length of PQ, QR and PR are 55.
Step-by-step explanation:
Given that the lengths in an equilateral triangle are all the same. We can assume that PQ = QR = PR. So we can choose any 2 lengths and compare it :
[tex]PQ = QR[/tex]
[tex]18x + 1 = 24x - 17[/tex]
[tex]1 + 17 = 24x - 18x[/tex]
[tex]6x = 18[/tex]
[tex]x = 18 \div 6[/tex]
[tex]x = 3[/tex]
Next, we have to substitute x = 3 into the expressions :
[tex]PQ = 18(3) + 1 = 55[/tex]
[tex]QR = 24(3) - 17 = 55[/tex]
[tex]PR = 15(3) + 10 = 55[/tex]

in a sport %53 of those surveyed belived their high school football team will win the state championship the poll shows a margin of error of 5 percentage points write and solve an absolute value in quality to find the least and the greatest percent of people that think their team will win the state championship
Answer:
Step-by-step explanation:
From the given information:
suppose, the total number of people = n
Thus, the percentage of people believe in high school = 53% = 0.53
= n × m
The poll also let us understand that the number of people falls in margin error.
= ±n × M.O.E
where;
M.O.E = margin of error = ±5%
∴
the number of people falls in margin error. = ±n × 0.05 = 0.05 n
Thus, we can posit that the greatest percentage of people think for highschool was:
[tex]( \dfrac{0.53 n + 0.05 n}{2}) \times 100= 54%[/tex]
However, the least percentage of people think for highschool was:
[tex]\mathbf( \dfrac{0.53 n - 0.05 n}{2}) \times 100= 48 \%}[/tex]

Select two options. (1.9, 2.5)
Answer:
2.2, -1.4 and 2.2, -1.35
Step-by-step explanation:
b and c
The points that are possible approximations on the graph are: (2.2, –1.4) (2.2, –1.35)
How to solve for the points in the graph
We have these equations
[tex]y = -\frac{7}{4} x+\frac{5}{2}[/tex]
[tex]y = \frac{3}{4} x-3[/tex]
From the picture we can see that these two lines intersected at a point on the graph.
This point of intersection is x, y.
The x coordinates are at 2, 3
The y coordinates are at -1, -2
From these points we can have approximations for this system as: (2.2, –1.4) (2.2, –1.35)

Find the area and circumference of a circle with a diameter of 10 in. Round to the nearest tenth for both values.
Answer: area = 0.1 m^2
Circumference = 0.8 m
Step-by-step explanation:
1 in = 0.0254 m
5 in = 0.0254 m × 5
5 in = 0.127 m
r = 0.127 m
Area of the circle = π r^2
= π × 0.127^2
= 0.05 m^2
=0.1 m^2
Circumference of the circle = 2 π r
= 2× π × 0.127
= 0.798 m
= 0.8 m
Answer:
1. A = 78.5 in²2. C = 31.4 inStep-by-step explanation:
1. area of a circle = πr²
2. circumference of a circle = 2πr
where diameter = 10 in.
radius = 10 / 2 = 5 in
1. area of a circle = π(5)²
= 78.5 in²
2. circumference of a circle = 2πr
= 2π(5)
= 31.4 in
A triangle has vertices on a coordinate grid at A(-8, -10), B(9, -10), and
C(9,-3). What is the length, in units, of AB?
Answer:
17
Step-by-step explanation:
The length of line AB is 17 units which is one side of a triangle.
What is a triangle?A triangle is a closed 2D figure formed by joining three non-co-linear points. By the property of sides, triangles are of three types they are:- Equilateral triangle, Isosceles triangle, and scalene triangle.
We know the length of two given pairs of points can be determined by the distance formula which is [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].
Given are the points of the vertices of a ΔABC are A(-8, -10), B(9, -10), and
C(9,-3).
∴ The length of line AB is,
= [tex]\sqrt{(9 + 8)^2 + ( -10 + 10)^2}[/tex] units.
= [tex]\sqrt{17^2}[/tex] units.
= 17 units.

the temperature dropped 2°F every hour for 6 hours. What was the total number of degrees the temperature changed in the 6 hours? Explain how you determined your answer.
Answer:The temperature dropped 12 degrees Fahrenheit total
Step-by-step explanation: The temperature dropped 2 degrees per 1 hour for 6 hours, so you would multiply 2 (degrees per hour) by 6 (hours the temperature dropped). 6 x 2 = 12
The total number of degrees the temperature changed in the 6 hours is 12°F.
Here,
The temperature dropped 2°F every hour for 6 hours.
We have to find,
The total number of degrees the temperature changed in the 6 hours.
What is Degree in Fahrenheit?
Fahrenheit is a scale for measuring temperature, in which water freezes at 32 degrees and boils at 212 degrees. It is represented by the symbol ° F.
Now,
The temperature dropped 2°F every hour for 6 hours.
1 hour = 2°F
6 hour = 6 x 2 = 12°F
Hence, The total number of degrees the temperature changed in the 6 hours is 12°F.

In a class of 60 students in an online test, where girls are twice the number of boys, mellisa ranked 27th from the top. If there are 9 boys ahead of mellisa, how many girls are after there rank?
Answer:
17
Step-by-step explanation:
60 students in total, that means girls are 40 in number and boys are 20 in number (because girls are twice the number of boys).
If girls are 40 in total
Boys are 20
With 9 boys ahead of melissa, that means ( we will use 26 because she is in 27th)
26-9 = 17
This means 17 girls are ahead of melissa.

Convert the following percent into common fractions in simplest form:
5 1/3%
Answer:
4/75
Step-by-step explanation:
you will get 5 and 1/3 percent equals (5 + 1/3) / 100 which is equal to 5/100 + (1/3) / 100 which is equal to 5/100 + 1/300. place both fractions under a common denominator. you will get 5/100 + 1/300 = 15/300 + 1/300 = 16/300. simplify the fraction to get 16/300 = 8/150 = 4/75

Answer:
ab = 42
Step-by-step explanation:
4x + 6 + 7x + 15 = 120
combine like terms
11x + 21 = 120
subract 21 from both sides
11 x = 99
x = 9
plug in to double check 9 in 4x + 6 + 7x + 15
meaning 4 times 9 + 6 + 7 times 9 + 15
36 + 6 + 7 times 9 + 15
Then simplify,
42 + 7 times 9 + 15
Then simplify again,
42 + 63 + 15
Then simplify one last time,
42 + 78
and your answer is
120
meaning the X is right so now plug in the X in 4x +6
and your answer is 42
