Answer:
W = X in.
L = (3x - 6) in.
A = L*W = (3x-6)X = 45,
3x^2 - 6x = 45
3x(x-2) = 45,
x(x-2) = 15,
x^2 - 2x - 15 = 0
(x-5)(x+3) = 0,
x-5 = 0,
x = 5 in.
x+3 = 0,
x = -3.
Solution Set: x = 5, and x = -3.
Select + value of X:
x = 5
W = x = 5 in.
L = 3x-6 = 3*5 - 6 = 9 in.

Answer:
c) 31
Step-by-step explanation:
Given: f(x) = 3x + 1
We are being asked to find the function's value for x = 10.
Substitute 10 as the value of x in the function:
⇒ f(x) = 3x + 1
⇒ f(10) = 3(10) + 1
⇒ f(10) = 30 + 1
⇒ f(10) = 31
Therefore, the function's value at x = 10 is 31.
