Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.
![A = l*w\\60 = w(w -4)\\60 = w^2-4w](https://tex.z-dn.net/?f=A%20%3D%20l%2Aw%5C%5C60%20%3D%20w%28w%20-4%29%5C%5C60%20%3D%20w%5E2-4w)
Subtract 60 from both sides and factor the quadratic to solve for w.
![w^2 -4w - 60 = 0\\(w-10)(w+6) = 0](https://tex.z-dn.net/?f=w%5E2%20-4w%20-%2060%20%3D%200%5C%5C%28w-10%29%28w%2B6%29%20%3D%200)
Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
I believe the answer is 7
Answer:
Step-by-step explanation:
First I just made -2/5 into a decimal because I like to work with decimals better (which equals -.4)
Then I times everything separately in the parenthesis and got -8x+6
Next you move the 6 over to the left side of the equals sign which would make the equation be -6 = -8x
Lastly you divide the -8 from -6 and you get X = 3/4
Answer: The answer is 12
Step-by-step explanation: because 5+5+2=12.
18/24 can both be divided by 6, so it's 3/4
