Answer:
31 over 3
Step-by-step explanation:
We are given the function <span>–2x – 4 + 5x = 8 and is asked in the problem to solve for the variable x in the function. In this case, we can first group the like terms and put them in their corresponding sides:
-2x + 5x =8+4
Then, do the necessary operations.
3x = 12
x = 4.
The variable x has a value of 4.</span>
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)
Answer:
(a, a+b).
Step-by-step explanation:
Midpoint = [(a+2b + a-2b)/2 ], [b-a + 3a+b]/2
= (2a/2, (2a+2b)/2
= (a, a+b).
Answer:
L = 18 inches
Step-by-step explanation:
if s is side length
400 = s•s•4
s² = 100
s = 10
so the original flat cardboard square has sides of
L = 10 + 4 + 4
L = 18 inches
