Answer: 4(10 +8) = 72
Step-by-step explanation:
You want to distribute the 18 and make it smaller so you change it to 10 + 8. Then you do 4(10) + 4(8) = 40 + 32 = 72
Answer:
7.1
Step-by-step explanation:
A = s**2
50 = s**2
s = 50**(1/2) = 7.07 rounded = 7.1

To divide 53 by 8 wont be possible so u find a number that when you multiply by 8 it gives u a number closer to 58 which is 8*6=48 i.e 53 divided by 8 is 6 rem, then to get the reminder you subtract 42 from 53 i.e 53–48=5 so the final answer will be 6 and 5/6
(goh)(x) = (g(x))(h(x)) = (x^2)(x-7) = x^3 -7x^2
then (goh)(5) = (5^3)-7(5)^2 = 124-7(25) = 124-175 = -51
