7x12= 84
1+6=7
12=12
So the area is 84
Answer:
Let's write this out in an equation.
y = 4 + 7x
Answer:
x=4
Step-by-step explanation:
1. 7x+56=14x+28 using distributive property (with the number of stes you need to have, this may count as 2)
2. 56=7x+28 by subtracting 7x from each side
3. 28=7x by subtracting 28 from both sides
4. x=4 by dividng by 7
5. plug back into equation
7(4)+56=14(4+2)
28+56=14(6)
84=84
I thought it was 100 because 5x2=10 10 to the 2nd power is 100 because 10x10=100
