The rectangle has two sides of length L and two sides of length W. The perimeter of the rectangle is the addition of all sides.
P = 2L + 2W
We are told the length is 6 more than 4 times its width. Therefore, we can write:
L = 4W + 6
We know the perimeter, and we can now substitute L into the perimeter equation and solve for W.
2L + 2W = P
2(4W + 6) + 2W = 102
6W + 12 + 2W = 102
8W = 90
W = 11.25 cm
We have solved the width as 11.25 cm and can now solve for the length.
L = 4W + 6
L = 4(11.25) + 6
L = 45 + 6
L = 51 cm
The length of the rectangle is 51 cm, the width of the rectangle is 11.25 cm.
Solving for b, we have the equation A(b)=12*(b+9)/2 - we cancel out 12 and the 1/2 to get 6(b+9)=A(b) and get 6b+54=A(b). Subtract 54 from both sides to get 6b=A(b)-54 and divide both sides by 6 to get b=A(b)/6-9 = A
Answer:
34 in 40
Step-by-step explanation:
6 in 40 is the probability of winning, so
34 in 40 is the probability of <em>not</em><em> </em>winning.
simply do 40 - 6.

Answer:
im pretty sure its 27.
Step-by-step explanation:
if g(x) = 20 then the new problem is 20=x-7
20=x-7 . add 7 to both sides
+7=+7 . +7 cancels out the -7
27=x . <<<answer
