Divide f(x) by d(x), and write a summary statement in the form indicated.

f(x) = x4 + 4x3 + 6x2 + 4x + 5; d(x) = x2 + 1

a. f(x) = (x2 + 1)( x2 + 4x + 5) + 12x - 15
b. f(x) = (x2 + 1)( x2 + 4x + 5)
c. f(x) = (x2 + 1)( x2 - 4x + 5)
d. f(x) = (x2 + 1)( x2 - 4x + 5) + 12x - 15

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
