Step-by-step explanation:
All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power. So the length of the edge of a cube with a volume of 125 is 5.
Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
Answer:
39 Would be your best guess since the literal percent is 38.95 or 38 19/30
Step-by-step explanation:
F(-5) = 2(-5) + 1 = -9
g(-5) = (-5)^2 = 25
(f*g)(-5) = -9(25) = -225
(50+ b)5
= 5* (50+ b) (commutative property)
= 5* 50+ 5* b (distributive property)
= 250+ 5b
= 5b+ 250
The final answer is 5b+ 250.
Hope it helps.
