Answer:
Step-by-step explanation:
3x=-15
x=-5
To find the answer, you convert the percentage to a decimal. 140% = 1.4
Then you divide 56 by 1.4
56/1.4 = 40
B
Explanation
I don’t have one
Answer:
C
Step-by-step explanation:
The expression given is a difference of cubes and factors as
a³ - b³ = (a - b)(a² + ab + b²)
8
= (2
)³ ⇒ a = 2
27
= (3y²)³ ⇒ b = 3y²
Hence 2 factors are
(2
- 3y²) and
((2
)² + (2
× 3y²) + (3y²)²)
= (4
+ 6
y² + 9
)
Hence the factored form of the expression is C
