Use the figure to find the measures.
Solve for x.

x = sqrt(5)

Step-by-step explanation:

The ratio of the areas is equal to the ratio of the side lengths squared

20      5^2

=

4          x^2

Using cross products

20 x^2 = 4 * 5^2

20x^2 = 4*25

20x^2 = 100

Divide by 20

20x^2 = 100/20

x^2 = 5

Take the square root of each side

sqrt(x^2) = sqrt(5)

x = sqrt(5)

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
