Answer:
D: x^2 + 7x + 4
Explanation:
To solve this, we have to replace the x in the equation to x + 2.
f(x+2) = (x+2)^2 + 3(x+2) - 6
Now we multiply the parenthesis with the number next to it.
f(x+2) = x^2 + 4x + 4 + 3x + 6 - 6
For the (x+2)^2, it becomes (x+2)(x+2), and in order to multiply them, use FOIL (First, Inner, Outer, Last). First, we multiply the first two numbers (x and x) to get x^2. Then, we multiply the inner and outer numbers (x * 2 and x * 2) to get 2x and 2x. then, we add those together to get 4x. After that, you multiply the last two numbers (2 and 2) to get four! So: (x+2)(x+2) = x^2 + 4x + 4!
Finally, you can simplify the numbers first by adding / subtracting similar numbers (numbers with the same exponent)
f(x+2) = x^2 + 7x + 4
Your answer is D!

which of the following is equivalent to (3^x+1)(3^x-1)^2/9^x for all x? a. 3^2x-1 b. 3^x c. 3^x-1 d. 3^x-2 e. 3^3-x
Answer:
[tex]3^{x-1}[/tex]
Explanation:
Given
[tex]\frac{(3^{x+1})(3^{x-1})^2}{9^x}[/tex]
Required
Find its equivalent
[tex]\frac{(3^{x+1})(3^{x-1})^2}{9^x}[/tex]
Expand the numerator
[tex]\frac{(3^{x+1})(3^{x-1})(3^{x-1})}{9^x}[/tex]
Apply law of indices: [tex]a^m * a^n = a^{m+n}[/tex]
This gives
[tex]\frac{3^{x+1+x-1+x-1}}{9^x}[/tex]
Collect like terms
[tex]\frac{3^{x+x+x+1-1-1}}{9^x}[/tex]
[tex]\frac{3^{3x-1}}{9^x}[/tex]
Express [tex]9^x[/tex] as a factor of 3
[tex]\frac{3^{3x-1}}{3^2^x}[/tex]
Apply law of indices: [tex]\frac{a^m}{a^n} = a^{m-n}[/tex]
This gives
[tex]3^{3x-1-2x}[/tex]
[tex]3^{3x-2x-1}[/tex]
[tex]3^{x-1}[/tex]
Hence,
[tex]\frac{(3^{x+1})(3^{x-1})^2}{9^x}[/tex] is equivalent to [tex]3^{x-1}[/tex]
Half the difference of 18 and a number n is equal to the sum of n and three. what is the value of n?
Answer:
n=12
Explanation:
First you have to write out the equation for the problem.
(18+n)/2=n+3
To get rid of the fraction, multiply both sides by 2.
18+n=2n+6
Now subtract n and subtract 6 from both sides and you will have your answer.
12=n
Answer:
n=4
Explanation:
(18-n)/2=n+3
2*((18-n)/2)=(n+3)*2
18-n=2n+6
+n +n
18 = 3n+6
-6 -6
12 =3n
÷3 ÷3
4=n
n=4
