You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.
The square root of 9 is 3 so we can just have
(which just means 3 times the square root of 7).
Answer:
i believe the first one should be 20 5 since its supposed to be in expanded form but i dont know the second one sorry hope you do good
Step-by-step explanation:
graph B ( the lower one )
for a function to be defined there can only be one value of y for each value of x
graph A has more than 1 value of y for given values of x
for example ( - 1, 4 ) and ( - 1, - 4 ) thus is not a function
graph B only has 1 value of y for a given value of x thus is a function

Answer: A) 1/10</h3>
=============================================
Work Shown:
(4/5) divided by 8
(4/5) divided by (8/1)
(4/5) * (1/8) .... flip the second fraction and multiply
(4*1)/(5*8)
(4*1)/(5*4*2)
1/(5*2) ... the '4's cancel
1/10
--------------
Alternative method:
4/5 = 0.8 when using a calculator or long division
(4/5) divided by 8 = 0.8/8 = 0.1
0.1 = 1/10
The digit 1 in 0.1 is in the tenths place, so that's why 0.1 = 1/10
Or you could use your calculator to see that 1/10 = 0.1
Another idea is to do
0.1 = 0.1/1 = 0.1/1.0 = 1.0/10.0 = 1/10
here I moved the decimal point 2 spots to the right for the numerator and denominator.
