Is there more to the question?
Answer:
c
Step-by-step explanation:
you have to find the surface area of all sides. so (11*11)*2 and (11*9) *4 with this you get c. 638in square.
We want to find y from the equation

Multiply each side by (y - 2).

Note that (y-2) in the numerator and denominator cancel out on the left side.
Therefore
3 = 8(y - 2)
3 = 8y - 16
Add 16 to each side.
3 + 16 = 8y - 16 + 16
19 = 8y
Divideach side by 8.
19/8 = y
Answer:
Answer:
1) -1
2) 3
3) 5
4) 9
Step-by-step explanation:
Plug the numbers in one at a time.
1) y= 2(-2)+3= -4+3= -1
2) y= 2(0)+3= 0+3= 3
3) y= 2(1)+3= 2+3= 5
4) y= 2(3)+3= 6+3= 9
Answer:
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Step-by-step explanation:
Simplifying
5 + -4 + 7x + 1 = 7x + 1
Reorder the terms:
5 + -4 + 1 + 7x = 7x + 1
Combine like terms: 5 + -4 = 1
1 + 1 + 7x = 7x + 1
Combine like terms: 1 + 1 = 2
2 + 7x = 7x + 1
Reorder the terms:
2 + 7x = 1 + 7x
Add '-7x' to each side of the equation.
2 + 7x + -7x = 1 + 7x + -7x
Combine like terms: 7x + -7x = 0
2 + 0 = 1 + 7x + -7x
2 = 1 + 7x + -7x
Combine like terms: 7x + -7x = 0
2 = 1 + 0
2 = 1
Solving
2 = 1
