Plzz help. Giving everything.<br> D. 24.5

Lemur [1.5K]

Answer:

$\frac{8}{14} = \frac{14}{x+2}$ (since they're similar, set them up as a proportion to find x)

14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)

196 = 8x +16 (subtract 16 from both sides)

180 = 8x (divide both sides by 8)

x= 22.5 (is your answer, or C)

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10x?

WARRIOR [948]

Answer:

x = $5 - \sqrt{31}$ , $5 + \sqrt{31}$

Step-by-step explanation:

6 = x^2 - 10x

0 = x^2 - 10x - 6

Let's use the quadratic formula. ( $x = \frac{-b +- \sqrt{b^2 - 4ac}}{2a}$ )

$x = \frac{10 +- \sqrt{-10^2 - 4(-6)}}{2}$

x = $\frac{10 +- 2\sqrt{31} }{2}$

= 5 +- $\sqrt{31}$

x = $5 - \sqrt{31}$ , $5 + \sqrt{31}$

Need help finding out what 3x=y and x-2y = 10

sweet-ann [11.9K]

Answer:

x=-2, y=-6

Step-by-step explanation:

Simple substitution.

Since y is isolated in one of the equations already, you can plug it into the second equation.

x - 2(3x) = 10

x - 6x = 10

-5x = 10

x = -2

Sub. x = -2 into 3x = y:

3(-2) = y

y = -6
