Answer:
9 feet
Step-by-step explanation:
The perimeter of a rectangle is 2(l + w) = p, where l = length, w = width, and p = perimeter.
- In this case, we're given the values of the width and perimeter: 2(l + 3) = 24
- We can solve this equation algebraically!
Step 1: Distributive the 2 to the terms inside the parentheses.
Step 2: Subtract 6 from both sides.
Step 3: Divide both sides by 2.
Therefore, the length is 9 feet.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
First step
5.(2x-8)
= (5.2x) + (5. (-8) )
=10x + (-45)
note :(+) . (-) = (-)
so + (-45)= (-45)
Add 15 to this equation
= 10x -40 +15= -15
=10x -25= -15
Leave x alone and make it positive
By the way, if you put (-25) in the right term, this number's notation (I mean -) will change
Namely
= 10x= (-15)+25
=10x= 10
x=1
Hope it helps :)
P.s. I dont know mathematical terms that's why i couldn't explain it properly but i tried to help as far as i can :)
Answer:
422.389 cm
Step-by-step explanation:
First you have to find the area of the circle then subtract it by the area of the rectangle. To find the area of the circle you have to square the radius then multiply it by 3.14.(12×12=144, 144× 3.14=452.389) Therefore 452.389 cm is the area of the circle. Area of the rectangle 30cm.
452.389 -30=422.389
