Need help been waiting for 2 hours to find a answer

1. 30 units squared and 22 units

2. 28 units squared and 28 units

3. 9 units squared and 12 units

4. 21 units squared and 20 units

Step-by-step explanation:

You just multiply by each parrallel for one 6 units high and 5 units wide, do this for 1, 3, and 4, but for 2 you have to break it into 2 shapes. Draw an extra line from (1,0) to (1, -2) then multiply each shape separately, then erase the line and count each block along the lines.

answer: '

the distance between points l and m

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
