Step-by-step explanation:
What other numbers are of this form have exactly four factors?
8 = 2³ has 4 factors 1, 2, 2², 2³
For any prime p, p³ has 4 factors 1, p, p², p³
Do all the perfect cubes have exactly four factors?
If p is not prime, then it is not true anymor
For instance, 8³ has more than 4 factors 1, 2², 2³,:
Is it true that all numbers that have exactly four factors are perfect cubes?
6 has 4 factors : 1, 2, 3, 6 but this is not a perfect cube.
Equation:
8 - 3 * x = 2 → we solve for 3 * x
8 - 3x = 2 → we take 8 to the right side of the equation
-3x = 2 - 8 → we solve for 2 - 8
-3x = -6 → we take -3 to the right side of the equation
x = -6 / -3 → we solve for -6 / -3
x = 2 → final answer
Proof:
8 - 3 * 2 = 2 → we solve for 3 * 2
8 - 6 = 2 → we solve for 8 - 6
2 = 2 → numbers are the same, meaning our equation is correct

A) x = 3y+6
3y = x-6
divide both sides by 3.
y = (x/3) -2
b) x = 5y-10
5y = x+10
divide both sides by 5.
y = (x/5) +2
c) x = y^2
square root both sides.
y = sqrt(x)
d) x = 2y^2 -4
x+4 = 2y^2
divide both sides by 2.
(x/2) +2 = y^2
square root both sides.
y = sqrt((x/2)+2)
e) x = (y-5)^2
square root both sides.
sqrt(x) = y-5
y = sqrt(x) +5
