Make the length x+4 and the width x and then make a formula x(x+4)=21
then u ll get x^2+4x-21=0 and then solve for x ..... the width is 3
Answer:
45
135
Step-by-step explanation:
x-y = 90
x = 3y
3y - y = 90
2y = 90
y = 45
x = 3×45 = 135
Answer:
85%
135%
Step-by-step explanation:
34/40=.85
.85 times 100= 85%
54/40=1.35
1.35 times 100=135%

Answer:
16 ft.
Step-by-step explanation:
A=LW
Area=Length times Width
We have the area and the Width.
112=Lx7
112÷7=L
L=16
The Length (n) is 16ft.
The customary units are the system of units of measurement used to measure things in the United States.
Length or distance includes units such as inch, foot, yard, and mile.
Here we have to convert 0.30 meter into customary.
We know that 1 meter = 39.37 inches
Now, using the unitary method we can find the number of inches in 0.30 meter.
The length 0.30 meter in customary is:
inches
Therefore, there are 11.811 inches in 0.30 meter, when converted into customary.
