Answer:
30
Step-by-step explanation:
You have to use the order of operations to solve this problem.
Steps:
1. solve the parenthesis first. 32/8=4
2. next is multiplication. 4.5(4)=18
3. lastly, do the addition. 18+12=30
I hope this helps.
Father's age = 3x
Son's age = x
3x + x = 76
4x = 76
x = 76/4
x = 19
The son is 19 yeats old.
X^2 + 16x + ?
a^2 + 2ab + b
(a + b)^2 which is a perfect square.
To find b to determine the last value, you divide 16x by 2x.
so:
b = 8
the last value would be 8^2 which is 64.
Hence answer is C - 64
The answer to this question is x = 0 if the x is an exponent on the base (7^2).
