Answer:
-1 is the value
Step-by-step explanation:
24 - 5² = 24 - 25
= -1
Answer:
y>5-x
Step-by-step explanation:
To solve this problem we need start by grouping terms in the same side of inequality.
Lets begging by grouping 'y' terms on the left side of inequality sign, to do this, subtract 3y to both sides:
2x+5y-3y>3y-3y+10
2x+2y>10
Now lets subtract 2x to both sides of inequality.
2x-2x+2y>10-2x
2y>10-2x
Now isolate variable x by dividing the inequaiity by 2.
y>5-x
That is the solution
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
