Answer:
Step-by-step explanation:
y = 2x - 3 --------------(i)
y = x² - 2x - 8 -----------(ii)
Substitute y = x² - 2x - 8 in equation (i)
x² - 2x - 8 = 2x - 3
x² - 2x - 8 - 2x + 3 = 0
x² - 2x -2x - 8 + 3 = 0
x² - 4x - 5 = 0
x² + 1x - 5x -5 = 0
x(x + 1) - 5(x + 1) = 0
(x + 1)(x - 5) = 0
x + 1 =0 ; x -5 = 0
x = -1 ; x = 5
When x = -1; y =2*(-1) - 3 = -2 -3 = -5
When x = 5; y = 2*5 - 3 = 10-3 = 7

Answer:
120 m
Step-by-step explanation:
Width - x
Length - 5x
x*5x = 500m²
5x² = 500 m²
x²= 500 ÷ 5
x²= 100
x = root 100
x = 10
Therefore width = 10
length 5*10 = 50
Perimeter = 2(l+w)
= 2(10 + 50)
=2*60
=120
