Answer:
a = ![\frac{2A}{p}](https://tex.z-dn.net/?f=%5Cfrac%7B2A%7D%7Bp%7D)
Step-by-step explanation:
Given
A =
ap ( multiply both sides by 2 to clear the fraction )

= a
Answer:
4a²(a² - 5)
Step-by-step explanation:
4a⁴ – 20a² =
4a²× a² - 4a²×5 = ⇒ common factor is 4a²
4a²(a² - 5) ⇒ factorized
To find the average, find the mean: add all the numbers together and divide by the number there is.
First add all the numbers together:
39 + 43 + 28 + 36 + 29 = 175
Next, divide 175 (the total) by 5 (because there are 5 numbers)
175/5 = 35
35 is your average.

Answer:
2x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -1
