Answer:
199 if it's 7b^3 + 10
9271 if it's (7b)^3 + 10
Step-by-step explanation:
You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.
So 3^3 is 27, 27*7 is 189, 189+10 is 199.
If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.
Answer:
7 > 24/4
Step-by-step explanation:
7 __ 24/4
simplify
7 __ 6
7 > 6
200 would be the average population density.
500/2.5=200
(2 + x) x (2x-5) = 56
(2+x)(2x-5)=56
2x² - x - 10 = 56
+10 +10
2x² - x = 66
2x² - x - 66 = 0
x = 6
2(6)² - (6) = 66
2(36) - 6 = 66
72 - 6 = 66
66 = 66
