Answer:
Step-by-step explanation:
This is a difference of squares.
√x^2 - √49 is the basic formula for factoring a difference of squares. The idea is that the middle term has been cancelled out.
√x^2 = x
√49 = 7
(x - 7)(x + 7) is the way this factors.
(x - 7)(x + 7)
===========
(x + 7)
The (x +7) in the numerator cancels with the (x + 7) in the denominator.
The answer is (x - 7)
====================================================
She might have wanted you to do it like this.
(x + 7) || x^2 + 0x - 49 || x - 7
x^2 + 7x ........... Subtract
==========
-7x - 49
-7x - 49 ...... Subtract.
=============
0
Or she might have seen you do this
x^2 - 49 x^2 49
======= = === - =====
x + 7 x 7
Every math teacher freaks when they see this. I hope I didn't put ideas in your head.
But if you got the answer by doing what I did, you got it right.

Hope this helps!

Greater number would be = 9 x 6 = 54
Smaller number would be = 9 x 5 = 45
Step-by-step explanation:
Given that the Greatest Common Factor (GCF) of two whole numbers is 9.
Also the ratio is 6:5.
As we know that GCF is the greatest number that divides the two number.
So, if the ratio of two number is 6:5 then the greater number would be:
Greater number would be = 9 x 6 = 54
Smaller number would be = 9 x 5 = 45
Both the number have the ratio of 6:5 (54/45 = 6/5) and have a GCF of 9.

Answer:
5(P - 1.00) + 3(P - 0.75)
Step-by-step explanation:
Cost of a package in store A = $P
Discount offered at store A = $1.00
Price paid per package at store A = Cost of a package in store A - Discount offered at store A
= P - 1.00
Cost of a package in store B = $P
Discount offered at store B = $0.75
Price paid per package at store B = Cost of a package in store B - Discount offered at store B
= P - 0.75
Total cost of 5 packages at store A and 3 packages at store B = 5(P - 1.00) + 3(P - 0.75)
