Make a word problem... I think.
Janie needs to knit 5 shirts. Maddy needs to make 12.5 shirts.They need to do this every day for 9.5 days. How many shirts in total (Maddy and Janie combined) do they make by the end of the 9.5 days?
Answer:
9.5 x (8 + 12.5)
9.5 x 20.5194.75 shirts in total

this person is approximately 72.0472441 inches tall because 1 meter is 39.3701 inches.
Answer:
957.85
Step-by-step explanation:
949.65
+ 8.2
_________
957.85
The given expression is in the form (a+b)(a-b) where
a = 5
b = sqrt(3)
Recall that
(a+b)(a-b) = a^2-b^2
is the difference of squares formula
If a = 5, then a^2 = 25
If b = sqrt(3), then b^2 = (sqrt(3))^2 = 3
The squaring undoes the square root. The two opposites cancel out.
So using a^2 = 25 and b^2 = 3, we can say
(a+b)(a-b) = a^2-b^2 = 25-3 = 22
Therefore,
(5+sqrt(3))(5-sqrt(3)) = 22
Answer: B) 22
<span>the answer:
the main condition can be found one of the following given methods:
if A = B*C*D, if we want to find the value of B, so B = A /C*D, the similar method can be applied to find the value of C an D. These are C= A/ B*D and D = A /C*B
in our case we have C = 2*Pi* R, if we want to find the value of Pi, it is Pi = C / 2*R
the true answer is D</span>
