Answer:
f(-3) = 18
Step-by-step explanation:
We need just substitute x with (-3) and calculate it.
f(-3) = (-3)² -2*(-3) + 3 = 9 + 6 +3 = 18
Answer:
32.59 (nearest hundredth)
Step-by-step explanation:

<u>Geometric sequence</u>
General form of a geometric sequence: 
(where a is the first term and r is the common ratio)
Given:
Therefore:
<u>Sum of the first n terms of a geometric series</u>:
To find the sum of the first 20 terms, substitute the found values of a and r, together with n = 20, into the formula:
Answer:
- The perimeter of the whole square is <u>19.79898987</u> (to be exact).
- The area of the whole square is <u>24.5</u>
(Use Sine and Cosine to find the side lengths.)
Hope this helped!! :)
Let's use a simple way. SPOE, APOE, DPOE, MPOE.
First, isolate the variable.
x5 + 3 = 2
-3 -3
x5 = -1/5 (5 divided by -1)
Answer to 5 divided by -1: -5.
A is the answer. (I'm pretty sure.)

~Realistic
1) given
2) definition of linear pair
3) definition of linear pair and supplementary
4) definition of supplementary supplementary angles add to 180
5) the measure of angle one plus the measure of angle 2 plus the measure of angle 3 equals 180
6) substitution in lines 4 and 5
7) the measure of angle one plus the measure of angle 2 equals measure of angle 4 by algebra and simplification
