Step-by-step explanation:
Let the length be L.
Let the breath be B.
So, we are given that
length of a rectangle is 7 inches greater than three times its width .
So, according to the Question,
L = 7+ 3B.
So, we know that:-
Area = Length× Breadth.
So, it will be
B × (7 + 3B) = Area.
So,
3B² + 7 is an expression to represent its area.
45/75 = 30/x
30*75 = 2250/45 = 50
EF = 50 in.
Answer:
the width is 470 ft and the length is 730 ft.
Step-by-step explanation:
Perimeter of a flag is 2l+2w
Let w = width
Let l = w+260
2(w+260)+2w=2,400
2w+520+2w=2400
4w+520=2400
4w=1880
w=470
So, the length would be 470+260, or 730
Therefore, the width is 470 ft and the length is 730 ft.
I hope this helped and have a good rest of your day!
Answer:
Below.
Step-by-step explanation:
7(x + 2) = 91
Distribute the 7 over the parentheses:
7x + 14 = 91
Subtract 14 from both sides of the equation:
7x = 91 - 14
7x = 77
x = 77/7 = 11.
For the first one it would be:
C(800)=600
The second would be:
C(200)=e
And the third would be:
C(s)=900
