0.890-0.05 = .840
.840/ 0.042 = 20
20 weeks

I can find a simplified expression for the perimeter of a square with a side length of (2x-4)

ELEN [110]

perimeter = 8x - 16

A square has 4 sides of equal length, multiply length of side by 4

perimeter = 4(2x - 4) = 8x - 16

What are the solutions of the equation x6 + 6x3 + 5 = 0? Use factoring to solve.

Sergeu [11.5K]

Solution:

we have been asked to find the solution of the equation

$x^6 + 6x^3 + 5 = 0$

It can be solved using factoring as below:

$x^6 + 6x^3 + 5 = 0\\\\substitute, x^3=y\\\\y^2+6y+5=0\\\\y^2+5y+y+5=0\\\\y(y+5)+1(y+5)=0\\\\(y+5)(y+1)=0\\\\y=-1,-5\\\\\text{substitute back }y=x^3\\\\x^3=-1,-5\\\\x=-1,\sqrt[3]{-5} \\\\\text{These are the only real solutions}\\$

Will give brainlist

Arturiano [62]

Answer:

C y = 4x + 5

Step-by-step explanation:

use y = mx + b

we need m and b to complete the equation.

m = slope

b = y-intercept (when x =0)

(0, 5) is the y-intercept because that's when x = 0

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{9-5}{1-0} = \frac{4}{1} = 4$

slope is 4

so... y = 4x + 5
