What is the intercept form of the equation y=6x^2+12x-144

Stells [14]

Answer:

y = 6(x + 6)(x - 4).

Step-by-step explanation:

y = 6x^2 + 12x - 144

y = 6(x^2 + 2x - 24) Factoring the trinomial in the parentheses ,we get:

y = 6(x + 6)(x - 4)

-4k^2-8k-3 = -3-5k^2

mel-nik [20]

$-4k^2-8k-3 = -3-5k^2 \\ \\ -4k^2 - 8k = -5k^2 \\ \\ 4k^2 + 8k - 5k^2 = 0 \\ \\ -k^2 + 8k = 0 \\ \\ 8k - k^2 = 0 \\ \\ k(8 - k) = 0 \\ \\ k = 0,8 \\ \\$

The final result is: k = 0, 8.

The measures of the sides of a triangle are 2x + 3, 8x – 4, and . Write an expression that describes the perimeter of the triang

tresset_1 [31]

Answer:

Step-by-step explanation:

Perimeter of a triangle is the sum of all the sides.

A triangle has 3 sides, so if we add up all the 3 sides lengths (given as expressions here) of the triangle, we will have the perimeter.

Perimeter = $(2x+3)+(8x-4)+(x^2)\\=2x+3+8x-4+x^2$

Now combining like terms we have:

$2x+3+8x-4+x^2\\=x^2+10x-1$

Answer choice C is the correct one.
