-(m-8) = -8m+29 I dont understand how to do the left side

Temka [501]

-(m-8)= -8m+29

-1(m-8)=-8m+29-------------Note: there is always an invisible 1 in front

-m+8=-8m+29---------------Subtract both sides by -8

-m=-8m+21-------------------Add both sides by +m

0=-7m+21---------------------Add +7m to both sides

7m=21 -------------------------Divide both sides by 7

m=3

Find the missing length. Give all answers in the simplest radical form.

Answer:

x = 2 $\sqrt{74}$

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

x² = 14² + 10² = 196 + 100 = 296

Take the square root of both sides

x = $\sqrt{296}$ = 2 $\sqrt{74}$
