What is the value of x
My name is Ann [436]
X=3



Explanation:

A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180

56+4x+112=180
168+4x=180

Subtract 168 from both sides

4x=12

Divide 4 from both sides

X=3


You can check by filling it in.


56+4*3+112=

12+56+112=180

Which expression is represented by the phrase"the square of x increased by the product of 8 and x
m_a_m_a [10]
"The square of x" means x^2, so we can eliminate options A and D.

"product of 8 and x" means that 8 and x are multiplied together (like 8x)

If x^2 is increased by 8x, we are adding x^2 and 8x together.

<span>B. x^2 + 8x</span>
