It would be A, C, and E.
I checked the dimensions, and E. 4 x 6 = 24
C. 8 x 12 = 96 and A. 6 x 9 = 54.
Hope that helps ya!
Answer:
y = 4x - 3
Step-by-step explanation:
The equation for a line is y = mx +c
We need to find m which is the gradient:
To do this pick any two coordinates on the line:
(1, 1) and (2, 5)
Next divide the difference of the y coordinates by the difference of the x coordinates:
5 - 1 / 2 - 1
= 4/1 = 4
so our gradient is 4
We'd write that as y = 4x + c
Next we need to find c which is the y-intercept
To do this just simply look for where the line crosses the y-axis
This is -3
So we'd write that as y = 4x - 3
Hope this helps :)
Vcone=(1/3)hpir^2
d/2=r
18/2=d/2=9=r
h=18
v=(1/3)(18)(pi)(9^2)
V=(6)(pi)(81)

Answer:
3n+10
Step-by-step explanation:
6(n+4)-4
PEMDAS
start with parenthesizes
6 x n = 6n
6 x 4 = 24
so we have
6n+24-4
subtract the 4
6n+20
simplify by dividing by common factor
6n/2 =3n
20/2 =10
3n+10
