Find the sum of 3b/b 2 and 12/b 2 and express it in simplest form
alexandr1967 [171]
\frac{3b}{b^{2}} + \frac{12}{b^{2}} = \frac{3b + 12}{b^{2}} = \frac{3(b) + 3(4)}{b^{2}} = \frac{3(b + 4)}{b^{2}}

Find the area of a rectangle having a perimeter of 182 yards and a width 20 yards shorter than twice its length
Studentka2010 [4]
Let the length be l in this equation.

We know that the perimeter of a rectangle is w2 + l2 = P

Width is defined in terms of length, so we know w = l2 - 20

We can substitute this value of w into the formula for perimeter to find the length.

(l2 - 20)2 + l2 = 182

l4 - 40 + l2 = 182

l4 + l2 = 222

l6 = 222

l = 37

So the length is 37. Now that we've found the length, we can go back to the Perimeter formula again and find width.

w2 + (37)2 = 182

w2 + 74 = 182

w2 = 108

w = 54

Width is 54. Now with both of these values found, we can calculate area with the formula l * w = A

37 * 54 = A

1998 = A

So the area of the rectangle is 1998 yards^2.

A bag contains 12 pennies, 9 nickels, 11 dimes and 3 quarters. A coin is selected at random from the bag. Find the probability.
steposvetlana [31]
Probablity=desiredoutcomes/totalpossibleoutcomes

see which ones fit
dimes and quarters are over 9 cents
there are 11+3 or 14 of them

total outcomes=12+9+11+3=35

probablity=14/35=2/5

probablity is 2/5
