We have on the top of the figure one semircle, on the bottom of the figure another semicircle, to the left of the figure a line segment, and to the right of the figure another line segment, then we have a total of two semicircles and two line segments.

Answer: Fourth option: two semicircles and two line segments

Answer:

Standard form: $x^3+3x^2-x-3$

Leading coefficient: 1

Step-by-step explanation:

$3x^2-x-3+x^3=\\x^3+3x^2-x-3$

The leading coefficient is 1 because the leading term is $x^3$ .

If f(x) = 2x^2 + 2, find f(5)

Well, following the order of PEMDAS, I got choice B. 52

For instance, when you plug in 5 for x, you get F(5)=2(5)^2+2.

Moreover, following PEMDAS, you're supposed to solve what's inside the parenthesis, but since there is no operation going on inside the parenthesis, then you simple move on to the exponent.

In this case, you square the number 5, which gives you F(5)=2(25)+2

After that, you Multiply (letter M in PEMDAS). This results in F(5)=50+2.

Finally, you add them, which results in F=52.

By the way, I noticed a mistake in your work. When multiplying 2 by 5, the answer is 10, not 20.

Anyway, hope this helped! :-)
