If g(x) = -4x + 5, find g(-3x).

1 answer:

4 0

Answer: 12x + 5

Explanation:

g(x) corresponds to x, so you plug -3x into x. That equals -4(-3x) + 5. Multiply to get 12x + 5. Because you can’t add a number with a variable to a whole number, that’s your answer. Hope this helps!

If a rectangle has an area of 2x^2+7x+3 find the perimeter

nikdorinn [45]

Perimeter of a rectangle = 6x + 8

Solution:

Given area of a rectangle = $2x^2+7x+3$

Let us first factor the given polynomial.

$2x^2+7x+3=2x^2+x+6x+3$

$=(2x^2+x)+(6x+3)$

Taking out common terms in the above expression

$=x(2x+1)+3(2x+1)$

Taking out common term $2x+1$ in the above expression

$=(2x+1)(x+3)$

$2x^2+7x+3=(2x+1)(x+3)$

Area of a rectangle = l × b

Therefore, $l=2x+1$ and $b=x+3$

Perimeter of a rectangle = 2(l + b)

$=2[(2x+1)+(x+3)]$

$=2(2x+1+x+3)$

$=2(3x+4)$

$=6x+8$

The answer is same if you take <em>l</em> = x + 3 and <em>b</em> = 2x + 1.

Hence, perimeter of a rectangle = 6x + 8.
