Wouldn’t u just subtract 7 from 19 since they have the same variable
Answer: 23+9h+h^2
Step-by-step explanation:
f(3+h)=(3+h)^2+3(3+h)+5=
= 3^2+2*3*h+h^2+3*3+3*h+5=
= 9+6h+h^2+9+3h+5=
= 23+9h+h^2
This is a Linear equation, which means it gives a straight line when plotted on a graph. Please make Brainliest! ☺
Answer: A. 30
Step-by-step explanation:
The formula for the area of a circle is pi*r^2, where r is the radius of the circle.
900pi = pi*r^2
Divide both sides by pi.
900 = r^2
Square root both sides.
r = +/- 30.
Since the radius cannot be negative, the answer is 30 units.
