One solution because when you switch the - to the other side it will be positive which will equal one and make it one solution.
Step-by-step explanation:
hope this helped you :)) !!
First of all, you would use the FOIL method for -5(a + 3). This means to just multiply -5 to all of the values in the parenthesis. This would equal:
-5a -15 = -55
Then after, you would add 15 for both sides and get -5a = -40
Divide by -5 on both sides, you get a = 8.

Answer:
Step-by-step explanation:
For it to be a parallelogram, opposite sides have to be of same length.
Using the expressions given, we can make 2 equations:
<u>Equation 1:</u>
<u>Equation 2:</u>
<em>Solving equation 2, we have x:</em>
<em>Plugging this value of x into equation 1, we can solve for y:</em>
So,
