Answer: Choice A
A trapezoid has only 1 pair of parallel sides, but a parallelogram has 2.
=============================================
Explanation:
These terms are just things you memorize. A diagram of two examples is shown below. The example shows a non-rectangular parallelogram, but you could go with rectangles or squares if you wanted to.
4y+5=-31 you subtract 5 from both sides so you get 4y=-36 then you divide by 4 from both sides so you get y=-9 and to check you put -9 in for y and multiply 4 and -9 add 5 to get -31
The answer would be C. this is because the graph shows an open circle, which means it is NOT “or equal to”, so there shouldn’t be a line under the sign. the arrow is also drawn pointing to the right, meaning x would be GREATER THAN 0.
The answer is B. x = 29
Here's how I solved for x.
Step 1: Simplify 
to 
. Which leaves us with 
Step 2: Add 21 to both sides. Which leaves us with 
Step 3: Add 
to get your answer: x = 29
