If f(x) = x^2 + 3x - 6, then f(x+2)=? a. x^2 + 1 b. x^2 + x + 1 c. x^2 + x + 10 d. x^2 + 7x + 4 e. x^2 + 7x + 12

Answers

Answer 1
Answer:

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!

x + y = 12 x - y = 10, the value of the x-determinant for the system shown is -2. Solution: determinant = (1*-1) - (1*1) = -2.

If 16 + 4x is 10 more than 14, what is the value of 8x ?A) 2
B) 6
C) 16
D) 80

Answers

Answer: C

Explanation:

C

Answer:

16

Explanation:


16+ 4x = 10+14=24
=> 4x = 24-16 = 8
=> 4x *2 = 8*2 = 16
=> 8x = 16

Which choice uses a nonrenewable energy resource to generate energy?.

Answers

Answer:

What uses nonrenewable energy resources to generate energy?

Nonrenewable energy sources include fossil fuel oil, nuclear energy, coal, and natural gas. When coal, oil, and natural gas are burned in a power plant, the heat is applied to water in order to create steam, which then turns the turbine in a generator, and produces electricity

Answers

Answer:While caecilians have scales similar to fish, most other amphibians have moist, permeable skin. This forces most species to live in moist or aquatic habitats; otherwise, they would quickly dehydrate as water is lost through the skin.
