Answer:
a. 10 inches
b. 8 inches
c. 
Step-by-step explanation:
a. At side 0, perimeter is 0*4 = 0 in. At side 2.5 inches, perimeter = 2.5*4 = 10 inches, a change of 10 - 0 = 10 inches
b. At side 1, perimeter is 1*4 = 4 inches. At side 3 inches, perimeter = 3*4 = 12 inches, a change of 12 - 4 = 8 inches.

Answer:
-1. is -3/7
Step-by-step explanation:
6×-4/11*7 ÷ (4/3×6/11)
-24/11×7 ÷ (4/3×6/11)
-24/77 ÷ (4/3×6/11)
-24/77 ÷ (24/3×11)
-24/77 ÷ 24/33
-24/77 × 33/24
-1/77 × 33
-33/77
-3/7
Y = 0.8
4x + 8y = 40
4x + 8*(0.8) = 40
4x + 6.4 = 40
4x = 40 - 6.4
4x = 33.6
x = 8.4
Answer:
8
Step-by-step explanation:
