Answer:
![6^4](https://tex.z-dn.net/?f=6%5E4)
Step-by-step explanation:
All you have to do for this is follow PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Substraction) Which is the order of operations.
First you do parenthesis,
, when you have a positive exponent outside a parenthesis like this, you add them together, and in this case, you get, ![(2^2)^2=2^4=16](https://tex.z-dn.net/?f=%282%5E2%29%5E2%3D2%5E4%3D16)
After that, you do the rest of the exponents as well as multiplication,
.
Now we plug in the 81 from our last step along with the 16 from the first step and multiply them together. ![3^4*(2^2)^2=81*16=1296](https://tex.z-dn.net/?f=3%5E4%2A%282%5E2%29%5E2%3D81%2A16%3D1296)
Then you just simply need to find which of the answers come out to be the result we got which is 1296. Out of these 4 possible answers,
ends up being equal to 1296 which means that is the correct answer.
Answer:
Tom weighs 70 pounds
Step-by-step explanation:
first, you have to set up your equation which would be, x + 3x = 280.
The x stands for Tom's weight and the 3x stands for three times Tom's weight for the dad. You would then add your like terms, then divide by 4 to get 70.
x + 3x = 280
4x = 280
280/4 = 70
x = 70
Hope this helps!

➷ Substitute the value for 'x' in every time you see x
1) y = -2(-2) + 6
y = 10
2) y = -2(0) + 6
y = 6
3) y = -2(2) + 6
y = 2
4) y = -2(4) + 6
y = -2
5) y = -2(6) + 6
y = -6
