Your Answer is C (25,25).

On the second tringle there is x+20

On the first there is 5x

This means the second triangle is 5+20=25

So both are 25

Hope this helps!

5x^(-2)-17x^(-1)+6<br> i’m so confused pls help<br> will give brainliest

laila [671]

It's a quadratic equation in disguise. If you let $y=x^{-1}$ , then $y^2=x^{-2}$ , and we can rewrite the equation as

$5y^2-17y+6=0$

Solve for $y$ however you like; we get $y=\dfrac25$ and $y=3$ .

But we want to solve for $x$ , so we have

$y=x^{-1}=\dfrac25\implies x=\dfrac52$

$y=x^{-1}=3\implies x=\dfrac13$

KL = 8x-5 and LM = 6x+3

Burka [1]

The answer is x=4.
set the equations up: 8x-5=6x-3
Subtract 6x from one side and then the other side 2x-5=3
Add 5 from one side and then the other 2x=8
Divide 2 on each side which gets you x=4

Rewrite the expression so that the GCF is factored completely: 2x^3y+18xy-10x^2y-90y

Agata [3.3K]

2x^3y+18xy-10x^2y-90y

= 2xy(x^2 + 9)- 10y(x^2 + 9)

= (x^2 + 9)(2xy - 10y)

= (x^2 + 9) 2y(x - 5)

= 2y (x^2 + 9) (x - 5)
