Answer:
(X-8) and (x+1)
Step-by-step explanation:
If we multibly then (X-8) (x+1)=0 =x^2-7x-8=0
1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10 <--width+width
4+4=8 <---length + length
10+8=18 <--total perimeter
18 * 9=162in^2 <--multiplied the height +perimeter of base
Lateral Area=162in^2
2) Same concept as the previous one
Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2
Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2
Answer:
Step-by-step explanation:
The volume of a cylinder is
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
We are given a diameter of 5, which means that the radius is 2.5. The height is 15. Filling in:
![V=\pi(2.5)^2(15)](https://tex.z-dn.net/?f=V%3D%5Cpi%282.5%29%5E2%2815%29)
which gives you, in terms of π:
V = 93.75π in³ or if you are multiplying in π,
V = 294.5 in³
Answer:
x= 60.4
Step-by-step explanation:
y = 60.4
z= 29.6
x= 60.4
By complementary angle rule
