4(-4) + 2 = -16 + 2 = -14
Answer:
5 pounds of potatoes is $3.75 1 pound is .75 cents
Step-by-step explanation:
Let's simplify them top to bottom.
6(x + 2) < x - 3
6x + 12 < x - 3
5x + 12 < -3
5x < -15
x < -3
This one checks out.
3 + 4x <= 2(1 + 2x)
4x + 3 <= 4x + 2
This is a problem. In no world is 4x + 3 ever less than or equal to 4x + 2. This one has no solution.
A=3/7 b=4....................
If you mean
3 times square root of 125 then go to AAA
if you mean ∛125 then go to BBBB
AAAAAA
3 times √125=3 times 5√5=15√5
BBBBBBB
∛125=5 or -5
