4 • (2 + 5)^2 - 52
= </span>4 • (7)^2 - 52
= 4 • 49 - 52
= 196 - 52
= 144
if multiply by 2
4 • (2 + 5)2 - 52
= 4 • (7)2 - 52
= 4 • 14 - 52
= 56 - 52
= 4
no the square root of 113 is rounded to 56x2
P(A/B) = P(A∩B) / P(B)
P(A/B) = (3/10) / (2/5) = 3/10 x 5/2 = 15/20 = 3/4

Answer:
44
Step-by-step explanation:
Substitute k = 1, 2, 3, 4 into the expression and sum the terms.
2(1)² - 4 + 2(2)² - 4 + 2(3)² - 4 + 2(4)² - 4
= 2 - 4 + 8 - 4 + 18 - 4 + 32 - 4
= - 2 + 4 + 14 + 28
= 44
