First subtract 78.2 from 287 and get 208.8. Then divide 208.8 by 0.5 and get x=417.6
Answer:
A = 200ft²
Info:
l = 2w
P=2[(2w)+w)
P = 60
A=w(2w)
Step-by-step explanation:
Since we know the value of the perimeter, it's actually easy to solve with the information listed above.
Firstly, since the equation has the same variable, you can actually add them or multiply. You can write the perimeter in a new way,
P=6w
which means w = , or 10ft.
Now we know the width you can get the length by multiplying it by 2. Let's get the rectangle area.
A=w(2w) or A=wl
A=10(2x10) or A=10(20)
A = 200ft²
Answer:
Step-by-step explanation:
Given
Width = 1.2 in when Length = 1 in
Required
Determine the length when width = 1 in
First, we need to determine the ratio:
--- (1)
Let the required Length be represented with L
So:
--- (2)
Equate (1) and (2)
Multiply through by L
Divide through by 1.2

Answer:
y = -1/4x+2
Step-by-step explanation:
The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.
