Answer:
If two planes are parallel, a line in one plane is parallel to a line in the other plane. A line that intersects one of two parallel lines intersects the other also. Through a point not in a plane are an infinite number of lines parallel to the plane.
Step-by-step explanation:
i hoped this helped I found it on the web. couldnt really understand the question. too much planes
We open the brackets
And use the laws of indices
-2x^2(-5X^2+4X^3)
Opening brackets
10X^4-8X^5 we get X^4 and X^5 because the terms we have
multiplied have common bases and therefore we have added the powers
Hence our answer is 10X^4-8X^5

The rate at which he pumps water is
.
To find the number of hours it takes to pump 0.9 million gallons, we can set a proportion.
.
The question asks for the time in hours, so convert 600 min to hours. One hour is 60 min.
You can express it as a decimal, fraction, or a percent.
Hope it helps!
Step-by-step explanation:
sum is addition
3/2+x=11/5+4 1/2
get x alone by using opposite operation to get 3/2 on other side of equal sign
3/2 is being added to x, so the opposite is subtracting
3/2-3/2+x=11/5+4 1/2-3/2
3/2 cancels out on the left
x=11/5+4 1/2-3/2
need same denominator, all denominators are factors of 10
2×5
multiply top and bottom of each fraction to get denominator of 10
(11/5)*(2/2)
(4/1)*(10/10) and (1/2)*(5/5)
(3/2)*(5/5)
multiply top and bottom and add
x=(22/10)+(4/10)+(5/10)-(15/10)
add all numerators
x=(22+4+5-15)/10
x=16/10
now simplifydivide by 2 on top and bottom
x=(16/10)÷(2/2)
x=8÷5
5/5 is 1, and there is 3/5 left
so x=1 3/5
