marta [7]

Answer:

x = 8

Step-by-step explanation:

a^{2} +b^{2} =c^{2} \\ so 8^{2} +b^{2} =\sqrt{80} ^{2}

rearrange the formula:

\sqrt{80} ^{2} - 8^{2} = b^{2}

80 - 64 = b^2

b^2 = 16\\b  = \sqrt{16}

\sqrt{16}  = 4

x = 4+4 = 8

Please Simplify 5(x - 6)
nordsb [41]

Our equation looks like:

5(x-6)

This means that we will need to distribute. This means that we need to multiply everything inside the parenthesis by the number outside of the parenthesis. (<em>Note: you only distribute when variables are involved.)</em>

(5 \cdot x)-(5 \cdot 6)

Simplify:

5x-30

We cannot simplify any further, so we know that our equation, until we know what x equals, is 5x - 30.
