Answer: See explanation
Step-by-step explanation:
a. how old is Cheryl?
Cheryl's age = d + 5
b. how old is Brandon?
d + 5 + 2
= d + 7
c. what was the difference in their ages 5 years ago?
Cheryl age five years ago = d
Brandon's age five years ago = d + 2
Difference = d + 2 - d = 2 years
d. what is the sum of their ages now?
Cheryl's age = d + 5
Brandon age = d + 7
Sum = d + 5 + d + 7
= 2d + 12
e. what will the sum of their ages be two years from now?
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Sum = d + 7 + d + 9
= 2d + 16
f. what will the difference of their ages be two years from now
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Difference = Brandon age - Cheryl age
= (d + 9) - (d + 7)
= 2 years.

Hello from MrBillDoesMath!
Answer:
x = -1/27
Discussion:
3 x^(1/3) -1 +2 = 0 =>
3 x^(1/3) +1 = 0 => (as -1 + 2 = 1).
3 x^(1/3) + 1 - 1 = 0 - 1 => Add -1 to both sides
3 x^(1/3) = -1 => (divide both sides by 3)
(3/3) x^(1/3) = -1/3 =>
x^(1/3) = -1/3 =>
x = (-1/3) ^3 =>
x = -1/27
Thank you,

Answer:
<h2>
3p+6
</h2>
Step-by-step explanation:
8p+7−(5p+1)
=8p+7+−1(5p+1)
=8p+7+−1(5p)+(−1)(1)
=8p+7+−5p+−1
=8p+7+−5p+−1
=(8p+−5p)+(7+−1)
=3p+6
and thats how you get the answer
