Answer:
y=x+4
Step-by-step explanation:
First you would need to apply the distributive property on the left side to get rid of the parenthesis. Then, you would need to apply the square root on both sides of the equation. Once this is done you would just need to solve for x.
Since
7 * 8 = 56
a good place to start could be
70 * 80 = 5,600
Then
72 * 80 = (70 + 2) * 80 = (70 * 80) + (2 * 80)
= 5,600 + 160 = 5,760
This number is larger than 5,590, so let's pick another factor smaller than 80 by subtracting away as many 72s as we need:
5,760 - 72 = 5,688 = 72 * 79
5,688 - 72 = 5,616 = 72 * 78
5,616 - 72 = 5,544 = 72 * 77
So the quotient is 77, and we have
5,590 = (72 * 77) + 46
I think it’s 45 because it’s look like
Answer:
B and D
Step-by-step explanation:
The surface area is the area of each face of the cube. The volume is the amount that will fill the cube. These are two separate processes which cannot give you the same measurement by calculating one part of the surface area. B is false.
Doubling the sides of the cube will not double the surface area. It will quadruple it. D is false too.
