4. For the three-step question that follows, provide your answer to each question in the given workspace. Identify each step with a coordinating response. Be sure to clearly label each part of yo response as Part A, Part B, and Part C.
Part A: Ava was asked to find the value of the expression 13t - 8r2 when t = -10 and r =
2. Her work is shown below, but she made a mistake. What was Ava's mistake?
13t - 8r2
13( - 10) - 80 - 2)
131 – 10) - 804)
130 - 8(4)
-138 - (4)
-552
Part B: Evaluate the expression correctly.
Part C: Show all of your work to support your answer to Part B.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
