Evan and Marshall are having a debate. Evan contends that the Pantheon is larger than the Parthenon in terms of area. Marshall contends the opposite. To settle their debate, they find satellite images of both ancient temples and juxtapose them on a single coordinate grid (shown below).

Looking at the graph, the radius of the Pantheon is

30

m

30m30, start text, m, end text. Let's find the area of the Pantheon, rounding our result to the nearest square meter.

Hint #22 / 3

To determine the area of the Parthenon, we'll need to find its length and width. Let's use the distance formula to find the length from

Evan should win the debate.Step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
