The person who commented before me is mostly totally right
<h3>(2-1) + 3² ÷ 3.</h3>
<em>To divide powers with the same base, subtract the exponent in the denominator from the exponent in the numerator. Subtract 1 from 2 to get 1.</em>
<h3>2 − 1 + 3¹</h3>
<em>Subtract 1 from 2 to get 1.</em>
<h3>1 + 3¹</h3>
<em>Calculates 3 to the power of 1 and gets 3.</em>
<h3>1 + 3</h3>
<em>Add 1 and 3 to get 4.</em>
<h3>4</h3>
The correct option is Alternative "C".
The answer is x = 0.5 To get this you do 9-7 which is 2 and then do 2 divided by 4 which is 0.5
A) 55 degrees.
The two red slashes show that both angle x and the 55 degree angle are congruent.
