Answer:9.072×10³
Step-by-step explanation:
A number is said to be written in a scientific notation or standard form if it is expressed in the form a×10n where 1 is less than or equal to a and a is less than 10 and n is an integer
9072 is more than 10
So 9072÷10=907.2
Still 907.2 is more than 10
So 907.2÷10=90.72
Still 90.72 is more than 10
So 90.72÷10=9.072
9.072 is less than 10
We divided 9072 by 1000 and 1000 as a power of ten is 10³
So the answer is 9.072×10³
Area of a circe = Pi x radius^2
Marco has ( d + 14.55 ) $
Step-by-step explanation:
Marco's mom gave him d dollars for his allowance one week.
Allowance of one week = d $
He also earned $ 1 4 . 5 5 for his newspaper route that week.
Earning of Marco by selling newspaper route that week = 14.55 $
Total earning = Allowance of one week + Earning of Marco by selling newspaper route that week
Total earning = ( d + 14.55 ) $
So Marco has ( d + 14.55 ) $
Answer: (r + 4)(r + 8)Alright, I would first rearrange the equation by bringing all your terms to one side by adding 12r and 32 to both sides. This will result in the rearranged equation:

You can then factor the equation into the two binomials:
(r + 4)(r + 8).
4 + 8 equals the b term, 12, and 4 x 8 equals the c term, 32.
Answer:
Step-by-step explanation:
let the smaller square be A, and the side is a
larger square is B, the side is a+3
Area(A)=a^2
Area(B)=(a+3)^2
a^2+(a+3)^2=425 in^2
a^2+a^2+6a+9=425
2a^2+6a=425-9
2(a^2+3a)=416 we divide by 2
a^2+3a=208
we solve the quadratic function
we will get two roots, a(1)=13, and the negative answer we will ignore
a=13 and the side of the larger square is 13+3=16
