Brianna and Chloe are dividing 815.75 /9. Brianna says that the first digit of the quotient is in the hundreds place. Chloe says it is in the tens place. Who is right? How do you know?

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

answer is  

a.

5.2 inches

hope you get this right.
