B
Step-by-step explanation:
8^2=64. -8^2 also =64.
Answer:
x=5 and y=5
Step-by-step explanation:
You "plug" one equation into the other, to get a new equation that only has one variable (x or y), then you can simplify that and have your answer.
So let's plug the first into the second:
First, we convert the first equation into an x=... form. For this one, this means moving the +y to the other side:
x = 10 - y
Now we substitute 10-y for x in the second equation:
So 2x+4y=30 becomes:
2(10-y) + 4y = 30
And simplify that:
20 - 2y + 4y = 30
20 + 2y = 30
2y = 30-20
2y = 10
y = 5
This is the first answer! If we put this into the first equation, we get:
x = 10 - 5 = 5
Now we have both answers, x=5 and y=5

Answer:
1048.32 or 432 pi
Step-by-step explanation:
12*12=144
144+(4/3 pi *6^3)
6*6*6=216
216*4/3pi=864/3
864/3=288
288*3.14(pi)=904.32
904.32+144=1048.32
(If you have the pi symbol the answer is 144+288=432pi)
The answer is 6, 4 divided by 2/3 =6
if you need to show your work just multiply by the reciprocal :)
