I did the math and (6,26) is the correct answer.
Answer:
x = P/8
Step-by-step explanation:
The perimeter of the blueprint is given by the equation :
P = 8x
We need to solve the above equation for x.
Dividing both sides of the equation by 8.

Hence, the value of x is P/8
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
The answer is b because there is a negative in the exponent and the number needs to be a single digit and 54 is double digit. hope this helps!
