Answer:
1. 10x^2 -4
2. 2a^5 + 5b
Step-by-step explanation:
1. Simplify 4(x^2 -1) to 4x^2 -4
then add that to 6x^2
2. 4a^5 - 2a^5 = 2a^5 and
4b+b = 5b
Answer:
y = 2x^2 + 16x + 11
Step-by-step explanation:
2(x + 4)^2 - 21
2(x + 4)(x + 4) - 21
2(x^2 + 8x + 16) - 21
2x^2 + 16x + 32 - 21
2x^2 + 16x + 11
Answer:
The solution is

Step-by-step explanation:
The given equations are

and

The graph of the two equations intersects at
as show in the graph in the attachment.
The point of intersection of the two graphs is the solution to system of equations.
Hence the solution is

I'm not sure I'm understanding the wording of the question, but if it's this:
Juice boxes come in a package with multiple juice boxes in each package. Three people bought 18, 36, and 45 juice boxes. What is the largest possible number of juice boxes per package?
Then the problem is just an involved way of asking what the greatest common factor of 18, 36, and 45 is, and the answer is 9, the difference between 36 and 45, which are both multiples of 9. Note that 18 is also a multiple of 9. One way to find the greatest common factor of three numbers is to factor all of them and find which prime factors they have in common.
Answer:
f(x) = -4x + 12
Step-by-step explanation:
y - 2x = -6x + 12
+2x +2x
f(x) = -4x + 12
