Answer:
Sandy should have evaluated (-2)³ as -8
Step-by-step explanation:
(-2)³ (6 - 3) - 5(2 + 3) = -8 · 3 - 5 · 5 = - 24 - 25 = - 49

Answer:
15
Step-by-step explanation:
Prime factorization of the numbers:
330 = 2 × 3 × 5 × 11
75 = 3 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
LCM(330, 75, 450, 225)
= 2 × 3 × 3 × 5 × 5 × 11
= 4950
GCD(330, 75, 450, 225) = 15
Answer:
PR=71

visualize:
P Q R
O-------------O-------------O
13 58
