Hey!!
here is your answer >>>
width is x
length is 3x + 8
perimeter = 128
2(x + 3x +8) = 128
2( 4x + 8) = 128
4x + 8 = 64
4x = 56
x = 14!.
width = 14
length is 50

2: A = b*h
A = 4.5*14
A = 63 m^2
3: A = 1/2*b*h
A = 1/2*4*13
A = 2*13 = 26 in^2
Answer: B) 6x - 6 = 15x + 15
Step-by-step explanation:
To find our answer, we need to first work out each equation.
A) 6x - 15 = 6x + 15
First, cancel out the equal terms.
6x - 6x - 15 = 15
-15 = 15
This statement is false.
B) 6x - 6 = 15x + 15
-9x = 21
x = -7/3
<u>This statement has one solution. </u>
C) 6x - 6 = 6x + 15
-6 = 15
This statement is false.
D) 6x + 15= 6x + 15
15 = 15
This statement has infine solutions.
