Since you're adding x feet to the length which is 12 feet:
New area: (12+x)10.5
ANSWER

EXPLANATION
The dimensions of a matrix is of the form:

The dimensions of the first matrix is

The dimensions of the second matrix is

Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.

Therefore the dimensions of the product is a 2×2 matrix.
Answer:
A
Step-by-step explanation:
(fg)(x) = f(x) × g(x)
= (x - 8)(x² + x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² + x - 1) - 8(x² + x - 1) ← distribute both parenthesis
= x³ + x² - x - 8x² - 8x + 8 ← collect like terms
= x³ - 7x² - 9x + 8 → A

Function h has the largest y-intercept which is 44
Step-by-step explanation:
Any linear function is represented in the form

Here b is the y-intercept of the linear function i.e. the constant term in the function.
We will compare all the functions with the general form we get
y-intercept of f(x) = 1
y-intercept of g(x) = 8
y-intercept of h(x) = 44
y-intercept of j(x) = 0
Hence,
Function h has the largest y-intercept which is 44
