Answer:
The width is 10 inches.
x(x + 3) = 70
x² + 3x = 70
Subtract 70 from both sides.
x² + 3x - 70 = 0
Factor the trinomial
(x - 7)(x + 10) = 0
Set each equal to zero.
x = - 7, - 10
Distance can't be negative so x = 7 is the right one. Now we plug in for the length (x + 3)
x + 3
7 + 3
10
Step-by-step explanation:
option c is correct
putting the value of slope and y intercept into the formula
y = mx + c
y = 1/4x - 1 { since m = 1/4}
-3, -4, -5, -6, -7, and -8.
