Answer: it will have three terms. It will be in the form ax^2 + bx + c
The "a" could be any number, but if it is "1", it will be left out.
The "+" sign is often a minus sign.
^2 means "squared" and is usually shown as an exponent, but my keyboard don't have that capability now.
Examples
x^2 + 5x +4
5x^2 +13x -6
2x^2 -11x + 15
Answer: 1384.74
Step-by-step explanation:
A=πr^2
radius=42/2=21
(3.14)(21)^2
3.14(441)
1384.74
The verb is a verb on the vets is a verb
SinA=8/17, so arcsin(8/17) is your angle of A (around 49 degrees). 90-A is your angle for B
We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
