Express the product of 2x squared plus 6x -8 and x+3 in standard form

ANSWER

The standard form is:

EXPLANATION

The given product is

We expand using the distributive property to get:

Expand the parenthesis;

This simplifies to

Standard form is when the polynomial is arranged in decreasing powers of x.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
