The area of the rectangle is 48 square centimeters. Choose the equation you can use to find the value of x. 7.02a 3

8x = 48
8 + 8 + x + x = 48
8 48 = x
8 + x = 48

answer: the value of x is 7cm

step-by-step explanation:

answer: your correct answer is b. d.

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
