Answer:
W = 17
L = 40
Step-by-step explanation:
To find the perimiter, we add 2L + 2W
So: 2L + 2W = 114
We also know that: L - 6 = 2W
So we can plug in L - 6 into the original equation
2L + L - 6 = 114
Add 6 to both sides
3L = 120
L = 40
Now we can solve for width using any of our equations. I'll use L - 6, because it's the easiest
L - 6 = 2W
40 - 6 = 2W
34 = 2W
17 = W
So
W = 17
L = 40
Answer:
cross-section
Step-by-step explanation:
prism is a type of three-dimensional (3D) shape with flat sides.
It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.
Answer:
3 +- 2i
Step-by-step explanation:
Volume = pi x radius^2 x height
400=3.14 x 4^2xheight
400=50.24h
400/50.24= h
7.96 = height
We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. at x =0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get:
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y= -1
This can be expressed as an ordered pair as (-1, -1)
