2(4w+7)=62 <br><br> Whats the answer how do I do it?

blondinia [14]

$2(4w + 7) = 62$

Divide both sides by 2

$\frac{2(4w + 7)}{2} = \frac{62}{2} \\$

$4w + 7 = 31$

Subtract both sides 7

$4w + 7 - 7 = 31 - 7$

$4w = 24$

Divide both sides by 4

$\frac{4w}{4} = \frac{24}{4} \\$

$w = 6$

Pythagorean Theorem:
a^2 + b^2 = c^2
Since you have the hypotenuse, you can change the equation to find the missing side.
a^2 - c^2 = - b^2
Insert your numbers:
9^2 - 10^2 = -b^2
What do you get?
