1. What is the value of x? Do not convert to decimal. Keep your answer in exact (radical) form. Show all of your work. This is P
lesya [120]

Answer:

The value of x is \sqrt{113}.

Step-by-step explanation:

It is given that hypotenuse is \sqrt{177}. So, the legs would be x and 8.

Let's use Pythagoras theorem,

a^{2} +b^{2} =c^{2}

Plug in the numbers to solve for x.

x^{2} +8^{2} =\sqrt{177} ^{2}

Simplify it

x^{2} +64 =177

Subtract both sides 64.

x^{2} =113

Take square root on both sides

x=\sqrt{113}

We can not simplify the radical.

So, let's keep this as answer.

Simplify to create an equivalent expression.<br> 8(10 - 6q) + 3(-7q- 2)<br> Choose 1 answer:
eduard
Answer: -69q+74

Step by step:
1. Use distributive property.

8⋅10+8(−6q) + 3(−7q − 2)

Multiply 8 • 10 then -6 • 8

80 - 48q + 3(-7q - 2)

2. Use distributive property again.

80 - 48q + 3(-7q - 2)

Multiply -7 • 3 then 3 • -2

80 - 48q -21q - 6

3. Simplify

Subtract 6 from 80 then subtract 21q from -48q.

-69q + 74


8(10 - 6q) + 3(-7q - 2) = -69q + 74
