Answer:
Volume of a rectangular prism can be found with the equation
v = length × width × height
They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...
18 inches = 1.5 ft
v = l×w×h
v = 3×2×1.5
v = 9 ft^3
Answer:
59%
Step-by-step explanation:
Answer:
1.x^2-5x
2.2x^2+15x+18
3. x^2+20x+18
Step-by-step explanation:
1. x(x-5) x*x-5*x = x^2-5x
2. (x+6)(2x+3) x*2x+x*3+6*2x+6*3= 2x^2+15x+18
3.(2x^2+15x+18)-(x^2-5x)=x^2+20x+18
Y=1/2x-2
To find the point where the two lines intersect they are set equal to each other so that x can be found:
2x-5=-x+1
2x+x=1+5
3x=6
x=2
If x is known, x can be plugged into one of the two equations to find y.
y=-x+1=-2+1=-1
This means the point where they intersect is (2,-1).
We also know that the slope has to be 1/2 because the slope has to match the slope of the line it is parallel to.
Putting this into point slope form, we get:
(y-(-1))=1/2(x-2)
Which can be simplified into slope intercept form:
y+1=1/2x-1
y=1/2x-1-1
y=1/2x-2
It’s the first one (2,2)(3,5)(4,0)
