Approximately 4 liters are in a gallon
Answer:
1. 6 x^2 - 28 x + 30
2. (x-6) (x+3)
b cannot see
4a 20 x^3 - 10x^2 ft^3
b 160 ft^3
Step-by-step explanation:
1. (2x-6) * (3x-5) =
6x^2 -18x-10x+30
6 x^2 - 28 x + 30 excellent job
2. x^-3x-18
what numbers multiply together to give -18 and add together to give -3
-1* 18 = -18 -1+18 = 17
-2 * 9 = -18 - 2 + 9 = 7
-3 * 6 = 18 -3 + 6 = 3
-6 * 3 = -18 -6 + 3 = -3
(x-6) (x+3) excellent
I cannot check part b because it is cut off
4. V = l * w * h
V = (8x-4) * x * 2.5x
(8x-4) * 2.5x^2
20 x^3 - 10x^2
if x=2
V = 20 (2)^3 - 10 (2)^2
V = 20*8 - 10*4
V = 160 - 40
V = 120 ft^3
Step-by-step explanation:
Given that,
The length of a ladder, H = 20 feet
The height of the wall, h = 15 ft
We know that,
h is perpendicular and H is hypotenuse
So,
Now using Pythagoras theoerm,
Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
