Answer:
a. what is the value of x?
x = 6
b. How long is FI ?
13 cm
c. What is the value of y?
y = 10
d. How long is EF?
e. What is the perimeter of parallelogram FIRE?
26 cm
Step-by-step explanation:
A. (3x - 5) = (x + 7)
= 3x - 5 = x + 7
= 3x - x = 7 + 5
= 2x = 12/2
= x = 6
B. (3x - 5) cm
= 3(6) - 5 cm
= 18 - 5 cm
= 13 cm
C. (2y - 7) = (y + 3)
= 2y - 7 = y + 3
= 2y - y = 3 + 7
= y = 10
D. (y + 3) cm
= 10 + 3 cm
E. What is the perimeter of parallelogram FIRE?
Sol.
13 cm + 13 cm = 26 cm
