The product of 4 times 'm' . . . . . 4m
2 more than that . . . . . . . . . . . . 4m + 2
You can use the distibutive property by breaking apart the bigger number (38) into 30 and 8. Now, you can do: (9 x 30) + (9 x 8)
I hope this helps!!!

The volume of the sphere is calculated through the equation,
V = 4πr³/3
Substituting,
900 in³ = 4πr³/3 ; r = 5.99 in
Then, solve for the surface area of the sphere by the equation, SA = 4πr²
SA = 4π(5.99 in)² = 450.80 in²
Thus, in the nearest whole number, SA was calculated to be nearly 451 in².
Question4: C, question 5: A
Answer:
B. -1
Step-by-step explanation:
If we have a parabola whose equation is:
The line of symmetry is calculated as:
Now, we have the equation 
and the line of symmetry is 
Where:
So, we can replace 
by -4 and 
by -2 and solve for 
using the following equation as:
It means that the equation of the parabola is equal to:
