Answer: (x + 7)(x - 7)
Explanation: If a variable is taken to an even power, that variable is a perfect square. In this case, x² would therefore be a perfect square.
Since 49 is also a perfect square, what we have here is the difference of two squares. That can be factored as the product of two binomials one with a plus in the middle and one with a minus in the middle.
In the first position will be the factors of x² that are the same.
So we have <em>x</em> and <em>x</em>.
In the second position we will have the
factors of 49 that are the same, 7 and 7.
(x + 7)(x - 7) is your answer which is a factored version of x² - 49.
1. g(-1) = -3
f(-3) = 2(-3) - 1 = -7
2. f o h(3) :-
h(3) = 3^2 + 1 = 10
f o h(3) = 2(10) - 1 = 19
3. f(-5) = -11
g(f(-5)) = g(-11) = -33
Answer:
Well, for (D), the answer would be 32.
Step-by-step explanation:
Because, 20 +12 =32. And 32 - 12 = 20. With the other ones that add, its the same way. You can just for example, if its -5 + b = -40, you can just go 5 - 40= which equals 35. Which should give you 40 if you add 35 and 5 together.
