Answer:MAFS.912.A-CED.1.1
The measures of three sides of a triangle can be represented by 2x, 3x - 5, and 4x + 2.
The perimeter of the triangle is 65 inches.
a) Give an equation to represent this situation.
b) Solve for x.
c) What are the three lengths of the triangle?
Answer
x=10
Step by step explanation:
It is a dilation to you would divide the known sides with each other.
8/2=4
16/4=4
So, you would then multiply 2.5 by 4 which would get you 10
preetty sure this is it, if its wrong then im sorry
Answer:
3s -4
Step-by-step explanation:
6s^2 +40s - 64
Factor out a 2
2(3s^2 +20s - 32)
Factor inside the parentheses
-4*8 =-32
3*8 -4 = 20
2 ( 3s -4 ) ( s+8 )
Answer:
13
Step-by-step explanation:
Use the pythagorean theorem where 12 squared plus 5 squared is the square of the hypotenuse. 12 squared is 144 and 5 squared is 25. 144+25=169. Taking the square root of 169 we get 13. Therefore the missing side is 13 units long.

Answer:
<em>x = -6</em>
Step-by-step explanation:
<u>Equations</u>
Solve the equation:
x + 6 = -x - 6
We must find the value of x that makes the identity above true.
Let's join all the variables on the left side and the numbers on the right side.
Adding x:
x + 6 + x = -x - 6 + x
The variables cancel out on the right side:
2x + 6 = -6
Subtracting 6:
2x + 6 - 6 = -6 -6
The 6 and -6 are canceled out:
2x = -12
Dividing by 2:
x = -12/2
x = -6
