Answer:
Step-by-step explanation:
× A = <u>4y + 2</u> = 2(4y/2 + 2/2) = 2(2y + 1) ≠ 4(y + 2)
✓ B = <u>4y + 8</u> = 4(4y/4 + 8/4) = 4(y + 2) = 4(y + 2)
× C = y + y + y + y + 2 =
y (1 + 1 + 1 + 1) + 2 = <u>4y + 2</u> = A ≠ 4(y + 2)
✓ D = 5(y + 2) – (y + 2) = 5(y + 2) – 1(y + 2) =
(5 – 1)(y + 2) = 4(y + 2)
✓ E = y + y + y + y + 2 + 2 + 2 + 2 =
y (1 + 1 + 1 + 1) + (2 + 2 + 2 + 2) =
<u>4y + 8</u> = B = 4(y + 2)
× F = 5(y + 2) – (y – 2) =
(5y + 10) + (-y + 2) =
(5y – y) + (10 + 2) =
4y + 12 = 4(y + 3) ≠ 4(y + 2)
OK
The first one would be
8.34625
The second one would be

Use the interior angle theorem
(7-2)180 = 900
900 / 7 = roughly 128.6
your answer is C
Follow PEMDAS. So, first the ( ) needs to be done first. So that now gives us
3^2 + 5 x 4 - 6/3. Next is exponents. So now we have 9 + 5 x 4 -6/3. Next we have to do multiplication. So now we have 9 + 20 - 6/3. Now we have to add. 29-6/3. 29-2 is 27. So, 27 is the answer.
