Percents to a decimal is easier to understand just take the percent so say it is 35% the decimal form would be .35 or 5% .05, and for the percent to a fraction just take the percent such as 30/100 and make sure it is in the simplest form to solve so that would be 3/10.
Answer:
(x + 5)^2 = (5 - 3)^2
Step-by-step explanation:
Given the equation;
x^2 + 10x + 22 = 13
We have;
x^2 + 10x = 13 - 22
x^2 + 10x = -9
Adding half of 10 to both sides and completing the square as usual, we have;
(x + 5)^2 = 5^2 + (-9)
(x + 5)^2 = (5 - 3)^2
Explain how you can use a straightedge and a compass to construct and angle that is both congruent and adjacent to a given angle?
Answer: for this you will simply have to use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.
I hope it helps, Regards.
G(-1) = -1+3
= 2
F(2) = 5(2) - 10
= 0
