I = PRT/100 where P = pricipal, R = rate and T = number of years. I = interest.
So answer is (3250 * 1.7 * 3) / 100 = $165.75
X^2 - 49 = (x + 7)(x - 7) = x^2 - 7x + 7x = 49 = x^2 - 49
You add 25 and 22 and it adds up to 47 so the answer is 47
The first answer.
Point P is at (50,-40) the distance from Q to P is 80 units which you can find by subtracting the x of Q (-30) from the x of P (50).
50-(-30)=80
It then tells you point R is vertically above point Q so you know your x value for R will be the same as Q.
Add your distance from Q to P of 80 units to the y value of Q because you are traveling up.
-40+80=40
R will have a point of (-30,40) and a distance of 80 units
B. they are directly proportional because she keeps taking 3 at a time to his 1 at a time.
