Answer:3/35
Step-by-step explanation:
This one isn't too hard, just plug in each value!
x = -1
y = -4(-1) + 3
y = 7
x = 0
y = -4(0) + 3
y = 3
x = 1
y = -4(1) + 3
y = -1
x = 2
y = -4(2) + 3
y = -5
Answer:
36 years old
Step-by-step explanation:
let x = age of Rachael
2x+3 = current ages combined
[(2x+3)+4]+4 = 75
2x+11 = 75
2x = 75-11
2x = 64
x = 32
Rachel is 32 years old. Isaac is 3 years older, which is 35 years old.

The perimeter of the rectangle based on the factors given is 46.
<h3>How to calculate the perimeter?</h3>
The area of the rectangle is given as (x² + 13x - 90). This will be:
= (x² + 13x - 90)
= x² + 18x - 5x - 90
= x(x + 18) - 5(x + 18)
= (x - 5)(x + 18)
The sides of the rectangle are 5 and 18. The perimeter will be:
= 2(l + w)
= 2(5 + 18)
= 46
The area of the rectangle is given as (x² + 24x - 81.
= (x² + 24x - 81)
= x² + 27x - 3x - 81
= x(x + 27) - 3(x + 27)
= (x - 3)(x + 27)
The sides are 3 and 27. The perimeter will be:
= 2(l + w)
= 2(27 + 3)
= 60
= (x + 1)² + 3(x + 1) + 2
= (x + 1)(x + 1) + 3x + 3 + 2
= x² + x + x + 1 + 3x + 5
= x² + 5x + 6
