Notice the picture below
whateve the length is, is 20 more than whatever the width is
so, the width is "w" units, so the length is w+20 units then
the perimeter is all lengths added, in this case length+length+width+width
or
2l + 2w which is the same as 2(w+20)+2w
now, the smaller side, width, if times 2
and the length, times 3
they give a perimeter of 240
so, one could say that
once you found "w", what is length? well, w+20
Answer:the answer is 1 i just did it
Step-by-step explanation:
In the given question , we have a function given , which is
And we need to find the value of y when x=5.
So we substitute 5 for x and solve for y, that is
And on rounding to the nearest tenths, we will get
So when x=5, y=0.4
Answer:
x= -1/2
Step-by-step explanation:
1. Create an equation
8x+4=0
2. Subtract 4 from both sides of the equal sign
8x = -4
3. Divide 8 from both sides of the equal sign to get x by itself
x= -4/8
4. Simplify
x= -1/2
