Answer:
18cm
Step-by-step explanation:
We have the length of the rectangle but we need to find the width which we'll call w. Area is a, l is length.
a = l * w
20 = 5 * w
divide both sides by 5 to cancel the multiplication by 5 on the right side
4 = w
The rectangle is going to have two sides that are the length of l, and two sides that are the the length of w. We're looking for the perimiter p.
p = 2l + 2w
p = (2 * 5) + (2 * 4)
p = 18
700,000 + 70,000 + 70
is your answer
hope this helps :D
(2) 2x
Bc you’re adding the imaginary one infront of the x.
(1) X squared + 25
Distribution
(3) 15x-30
Distribution
(1) x to the 6 power
You add the powers when they are being multiplied
(2) 2x squared + 7x + 12
Foil method
(2) 9x + 20
Adding Like terms
(4) 12x + 25
Adding and multiplying like terms
(2) 19x + 7
Multiplying then adding like terms.
I hope this helps ;)
