Answer:
A) 2x*2 +6x -3x - 9= 2x*2 +3x -9
B) 2yx*2 +2yx +2y +3x*2 +3x +3
C) 36x*2 y +48yx +3xy*2 + 4y*2
D) 2x*3 - 4x*2 y + 3x -6y
Answer:
h(2)=6
Step-by-step explanation:
just plug in 2 where you have an x, and you’d have 2 + 6, which equals 6
Kilometers is for distance, and kilograms is for solids
Answer:
7x + 6 =8x - 6
x= 12
Step-by-step explanation:
- put them equal to each other
- then subtract 8x from both sides
- 7x(-8x) + 6 = 8x(-8x) - 6
- to get -1x
- then subtract 6 from both sides
- you'll get -1x = -12
- then divide -1 to both sides
- then you get x = 12
Answer:
V = 3,386,880 cubic yards
V = 91445760 cubic feet
V = (1/3) · b2 · h so 1/3 x 756^2 x 480 = 91445760 ft^3
Answer = 91445760 ft^3
Step-by-step explanation:
converting feet into yards
let
1 yard = 3 ft
1 ft = (1/3) yard
a = 756 ft = 756*(1/3) yards the length of the side of the square base
h = 480 ft = 480*(1/3) yards the height of the pyramid
a.) the volume of the pyramid V = (a^2*h)/3 = (a^2*h)(1/3)
V = (756*(1/3))^2*480*(1/3)*(1/3)
V = 3,386,880 cubic yards
