Answer:
For the expression if they don't want you to include the variables then I would write 3.14(6 + 4) or 3.14(2*3+2²). For the surface area, your answer is 31.4 units.
Step-by-step explanation:
If r = 2 and s = 3, then just plug them into the equation 3.14(rs + r²)
3.14(2*3+2²)
= 3.14(6+4)
=3.14(10)
=31.4 units for the Surface Area
-2n-7>-25
-2n-7=-25
add seven to each side
-2n=-18
divide by negative two
n=9
hope this helps!
For this case we must find the value of "x" of the following equation:
So:
We add 9 to both sides of the equation:
We apply square root on both sides of the equation to eliminate the exponent on the left side:
Thus, the solutions are:
