Answer:
B
Step-by-step explanation:
The equation is (2x+5)^2.
It can't be A because 2 is the multiplier for only x.
It can't be C because the square is outside of the equation.
It can't be D because again, the square is outside of the equation.
So the only thing left is B.
Hope this helped!
2. x =(6+√20)/-8=3/-4-1/4√ 5 = -1.309
Answer:
The slope for this equation is
.
Step-by-step explanation:
x y
point 1: -4 -3
point 2: 3 -2
slope: 
To solve for slope here is an equation, to help: 

You multiply it with the same number you use for the denominator.
in this case 3/4 and 7/10
you find the LCM of the denominator is 20
so for 4 to become 20 you multiply by 5 then for the numerator 3 also multiply by 5, so you get 15/20
its the same also with 7/10, you multiply both the numerator and the denominator by 2 and get 14/20
hope it help... :)
volume of cylinder = PI*r^2*h
r=11
h=15
using 3.14 for pi
3.14*11^2*15 = 5699.1 units^3
