Answer:24 i believe
Step-by-step explanation:
B. Associative Property
, you're working out the numbers in the parentheses before anything else.
Answer:
x = -25
x = infinite solutions
Step-by-step explanation for 1:
4(-25) - 10 = 5(-25) + 15
-100 - 10 = -125 + 15
-110 = -110
Step-by-step explanation for 2:
Both equations are the exact same. So whatever number you put, the answer will be right
Answer:
(a-1) *(a^2 +a-1) (a+2)
Step-by-step explanation:
a^4+2a^3-a-2
Lets factor by grouping
a^4-a + 2a^3-2
Factor out an a from the first group and a 2 from the second group
a(a^3 -1) +2(a^3-1)
Factor out (a^3-1)
(a^3-1)(a+2)
We need to recognize that a^3-1 is the difference of cubes
(x^3-y^3) = (x-y) (x^2+xy+y^2)
Let x=a and y=1
(a-1) *(a^2 +a-1) (a+2)
