To simplify the expression, we distribute terms accordingly. It is done as follows:
<span>(3a – 4b)(a + b)
3a</span>² + 3ab -4ab -4b²
3a² - ab -4b²
Therefore, the correct answer is option A, <span>3a^2– ab – 4b^2.

A trapezoid. The tom and bottom are parallel to each other as the sides are congruent. The top to angles are greater than 90 degrees (obtuse) and the bottom two angles are less than 90 degrees (acute).
Hey there,
This question is asking us to find the slope using the given points. In order to do that we use the equation:
Now we use the points and plug them into the equation above:
= 
Therefore the slope of the line that passes through the points (-7, 5) and (-2, 3) would be 
Hope I helped,
