Answer:
C) x = 1 / 2
Step-by-step explanation:
Formula for volume of a cube = a^3 ('a' to the power 3 or 'a' cubed)
a = side
Since volume = 1/8 ,
cube root of 1 / 8 will equal the side of the cube(which is 'x').
cube root of 1 / 8 = 1 / 2
answer = 1 / 2
The answer is x<-3
Step-by-step explanation:
4x+6<-6
-6 -6
4x>-12
÷4x. ÷4×
x<-3
Answer:
b = S - a - c
Step-by-step explanation:
You just move every other term except for the one you're solving for to the other side, using the opposite operations
S = a + b + c
S - a = b + c
S - a - c = b
b = S - a - c
OR
S = a + b + c
-b + S = a + c
-b = -S + a + c
b = S - a - c (we flipped all signs here to make b positive, like it's supposed to be. The justification for this is multiplying both sides by -1)
Answer:
- 11x² + 4x + 14
Step-by-step explanation:
Given
(9 - 3x²) + (- 8x² + 4x + 5) ← distribute both parenthesis by 1
= 9 - 3x² - 8x² + 4x + 5 ← collect like terms
= - 11x² + 4x + 14 ← sum of the polynomials
