Step-by-step explanation:
Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)
=============================================================
Explanation:
We can write the 9x^2 as (3x)^2 since
(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2
The 49 can be written as 7^2 because 7^2 = 7*7 = 49.
This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.
The difference of squares factoring rule is
a^2 - b^2 = (a-b)(a+b)
which we have a = 3x and b = 7 in this case
So,
a^2 - b^2 = (a-b)(a+b)
(3x)^2 - 7^2 = (3x-7)(3x+7)
9x^2 - 49 = (3x-7)(3x+7)
Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.
The power to a power rule is : KEEP THE BASE AND MULTIPLY THE POWERS.
Ex. (x^3)^4 = x^(3*4) = x^12
So ....
(7^10)^5 = 7^50
Last option is correct.
Answer:
1.5 is the value of C
Step-by-step explanation:
first step is by collecting the like terms:
5c+ct3c=9c
-11--3+2=-6
9c-6
9c=6
Divide both side by 6
you'll end up with 1.5.
