20×3 is 60 and if Sarah counted 45 beats in 20 seconds you'd multiply 45 by 3 so it would be 135.
Answer:
Three times the sum of a number and 2.
Step-by-step explanation:
Sum of a number and 2 = x + 2
3 times = 3 multiplied
Rotating 180° would be changing (x to -x and y to -y) therefore, X’ (-3, -4)
First, you have to apply the Pythagorean Theorem to this problem to solve for the hypotenuse.
22^2 + 15^2 = c^2
"C", which is the hypotenuse, is approximately 26.63 inches long. So, now add all the sides, and you should have 63.63 inches as your final answer.
