4a²=144
a²=144/4
a²=36
a=⁺₋√36
a=⁺₋6
Answer: we have two values for a; a=-6; and a=6
we check it out:
if a=-6
4(-6)²=4*36=144
if a=6
4(6)²=4*36=144
Answer:
30
Step-by-step explanation:
We need to figure out what 5 and 2 really mean in this scenario. So we add them together. 5+2=7
We then divide 42 by 7. 42/7=6
Afterward we multiple 5 by 6 to get the real number or servers. 5x6=30
And as a bonus (and also to check our work) we multiple 2 by 6. 2x6=12
5/2=30/12
Answer: 3y+7x=4.
Step-by-step explanation: took the test
Answer:
Step-by-step explanation:
What variable are you solving for?
-4x+y=29
y=29-(-4x)
y=29+4x
y=4x+29
----------------
-4x=29-y
-4x=-y+29
x=1/4y+29/-4
y=1/4y-29/4
