Marla did 64 sit-ups each day for one week. Use the distributive property to sow an expression you ca. Use to find the total num
ELEN [110]

Answer:

Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448

Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448

Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448

Step-by-step explanation:

Marla did 64 sit ups each day for one week = 64 *7 = 448

A distributive property allows us to multiply a sum by multiplying each addend separately first and then summing the products together.

64 sit ups could be written as 60+4, 50+14 or 40+24.

Apply the distributive property:

Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448

Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448

Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448

We can try any two numbers whose sum is 64 and all will give us the answer 448....

<span>Solve for r.

A = ½r²y
</span>


A=  \frac{1}{2}r^2y \\  \\ A*2= r^2 y \\  \\  \\  \dfrac{2A}{y}= r^2   \\  \\  \\   \sqrt{ \dfrac{2A}{y}} = r
