A rectangle has a length that is 5 inches greater than its width, and its area is 104 square inches. The equation (x + 5)x = 104 represents the situation, where x represents the width of the rectangle. (x + 5)x = 104 x2 + 5x – 104 = 0

Step-by-step explanation:

area = length x breadth

length = 5 inches greater than width = 5+x

width = x

area = (5+x) x

104 = (5+x) x

104 = 5x + x²

x²+5x-104 =0

looking for two numbers that when you multiply gives 104, and adding it gives +5

the numbers is 13 and 8 (-13, +5)

x²+5x-13x-104 =0

x(x+5)-13(x+5) = 0

(x+5)(x-13)=0

x+5 =0          x-13 =0

x = -5,             x=13

x= -5, 13

the width is either -5  or 13 inches

the length = (5+x) = (5+(-5)) = 5-5 =0

                     (5+x) = (5+13) = 5+13 = 18

lenth is 0 or 18 inches

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
