I’m confused on this one

$6\sqrt2$

Why?

We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

$h^2=6^2+6^2\\\\h^2=36+36\\\\h^2=36\cdot2\to h=\sqrt{36\cdot2}\\\\h=\sqrt{36}\cdot\sqrt2\\\\h=6\sqrt2$

In general, the formula for calculating the hypotenuse in an isosceles right triangle is $h=a\sqrt2$

a - a leg, h - a hypotenuse

8x + 2x - 5 = -35 <br><br> Can someone help me with this answer and how to show my work?

SashulF [63]

The answer is X= -3 and the work is 8x+2x-5= -35 so the -5 turns to a positive 5 and cancels itself it out so -35 becomes -30 then you add 8x and 2x then you get get 10x then you divide -30 by 10 and you get -3
