I'll draw a diagram for you, so that it's easier to understand.
First you have to understand that the perimeter is all the sides add up together.
Let's set up an equation, using l for the length, and w for the width.
5w + w = 48
Simplify
6w = 48
Divide by 6 on both sides
w = 8
Now the value we got is actually both widths (the green sides), so the width is actually 4. Which means that the length is 20.
The answer is
4ft by 20 ft.Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
Hello again!
So just like in the last problem you would do the same here.
Solve for 3y + 6 = 3
Subtract 6 from both sides.
3y = -3
Divide by 3.
y = -1
Now plug it into 8y + 2.
8(-1) + 2 = ?
-8 + 2 = ?
= -6
I hope this helps love! :)
Answer:
The movers will need 3 crib-jacks
Step-by-step explanation:
Since each crib jack can lift 30,000lbs, and without the belongings it only weighs 90,000, which divided by 30,000 equals 3.
In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.
But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.
The difference between five 3s the first time and one 3 the second time
is your 12 .
