Step-by-step explanation:
Area=(a+b)/2 x h
a=6x+3
b=4x-5
h=-5x+10
Area= -25x^2+55x-10
Answer:
Area = 81; Side Length = 3
Step-by-step explanation:
The area of a square is the side lenght squared, and 9² is 81.
The side lengh can be found by taking the square root of the area. √9 = 3
Since the radius is the same but the height changes, the volume would change by the multiple of the height.
In this case the volume of the larger cone would be 4 times as large as the smaller cone so you would need 4 small cones
Equation:
y + 2 = 1/3(x+1)
Assuming you are solving for Y:
y + 2 = 1/3(x) + 1/3(1)
(y + 2) - 2 = (1/3x + 1/3) - 2
y = 1/3x + 1/3 - 2
<u>y = 1/3x - 5/3</u>
