A rectangle has a height of 6k3 and a width of 2k2 + 4k +5.

Trava [24]

Answer: $12k^5+24k^4+30k^3$

Step-by-step explanation:

Given : The height of the rectangle = $6k^3$

The width of the rectangle = $2k^2+4k+5$

Formula : Area = height x width

Therefore , the area of triangle in terms of polynomial will be :

$6k^3\times( 2k^2+4k+5)\\\\= 6k^3(2k^2)+6k^3(4k)+6k^3(5)\ \ [\text{Using Distributive property}]\\\\=12k^{3+2}+24k^{3+1}+30k^3\ \ [\text{Using exponents rule}:\ a^n\times a^m=a^{n+m}]\\\\=12k^5+24k^4+30k^3$

Hence, the area of the entire rectangle = $12k^5+24k^4+30k^3$

The slope of the line below is -5 which of the following is the point-slope form of the line (2,-8)

insens350 [35]

The point slope form has the following syntax.

$y - y_1 = m(x - x_1)$
m = slope = -5
$y - y_1 = -5(x - x_1)$
(x,y) = (2,-8)
$x_1 = 2$
$y_1 = -8$
$y - y_1 = -5(x - x_1)$
$y - (-8) = -5(x - 2)$
$y + 8 = -5(x - 2)$ <------Answer
