Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side
Answer:
length = 13 ft
Width = 3 ft
Step-by-step explanation:
Width = w ft
Length = ( w +10 ) ft
Area = 39 square ft
length * width = 39
(w +10)* w = 39
w *w + 10*w = 39
w² + 10w - 39 = 0
w² + 13w - 3w - 3*13 = 0
w(w + 13) - 3(w + 13) = 0
(w + 13) (w - 3) = 0 {Ignore w + 13 , as measurement cannot be in negative}
w - 3 = 0
w = 3
length = 3 +10 = 13 ft

Answer: MH = 7</h3>
=====================================================
Explanation:
The double tickmarks for quadrilateral MATH show that MA = TH. Since TH is 5 units long, this makes MA the same length as well.
For quadrilateral ROKS, we have RO = 15. For "MATH" and "ROKS" we have "MA" and "RO" as the first two letters of each four-letter sequence; meaning that MA and RO correspond together.
The ratio of the corresponding segments is RO/MA = 15/5 = 3.
The larger quadrilateral has each side length 3 times longer than the smaller quadrilateral's corresponding side lengths.
--------------
In short,
larger side = 3*(smaller side)
--------------
Using this scale factor of 3, we can find MH
larger side = 3*(smaller side)
RS = 3*(MH)
21 = 3*MH
3*MH = 21
MH = 21/3
MH = 7
Answer:
In this picture I see a circle a rectangle a square.
Step-by-step explanation:
Answer: Terry paid $18.36 for the sweater.
Step-by-step explanation:
Given: Sales price of sweater = $24
Coupon states 
off the sales, i.e. Terry will get 
discount.
Also, tax rate = 6%
Tax will be charged = 6% of Sales price of sweater
= 0.06 x 6
= $0.36
Now , Final amount for Terry = Sales price - discount +tax
= $(24-6+0.36)= $18.36
Hence, Terry paid $18.36 for the sweater.
