Answer:
I think its B 252yd^2
Step-by-step explanation:
i got 254 so it might be 252
alright so you need to find the unit rate for both of these bought items.
5.25(5 1/4) pounds is equal to $2.10 if you set it into an equation
5.25x = $2.10
x represents how much is the price for one pound of banana
to find x you divide $2.10 by 5.25
you can either plug that into a calculator (.4 is the answer)
to divide a fraction
2.10 / 1 ÷ 21/4
switch the 21/4
2.10/1 ÷ 4/21
instead of using division to solve this you actually multiply!(don't ask me why)
2.10 × 4 = 8.4
21 × 1 = 21
now divide 8.4 by 21 = $0.4 for each pound of bananas
do the same on the other persons payment
3.25x = 6.5
x = 0.5
now you answer it. which one is cheaper?
Answer:
x - 3
Step-by-step explanation:
Given
Note that x² - 9 is a difference of squares and factors as
x² - 9 = (x + 3)(x - 3), thus
Cancel the x+ 3 factor on the numerator/ denominator leaving
x - 3 ← in simplified form

Answer:
It is a right triangle.
Step-by-step explanation:
By the Inverse Pythagoras Theorem if 39^2 = 36^2 + 15^2 then it is a right triangle.
39^2 = 1521
36^2 + 15^2 = 1296 + 225 = 1521.
So it is a right triangle.
