Factor the expression
(x+2)^2-25y^4

Consider the following equation -167 + 37 = 49 - 21p select the equation that has the same solution as the given equation. o a. p - 5 + ip = 7 - p ob. +55 + 12p = 5p + 16 c. 2 + 1.25p = -3.75p + 10 d. -14 + 6p = -9 - 6p reset next

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle
