Answer:
a ^ 2 - b ^ 2 = ( a + b ) ( a - b ) where a = 4p and b = 3q.
( 4p + 3q ) ( 4p - 3q )
5c+4 is equivalent
Its just simplified.
Answer:
x = -15
Step-by-step explanation:
7 + (2/5)x = 1
First, divide two by five to get 0.4, then substitute in the choices given (remembering that you must also add seven afterward).
0.4*-15 = -6 -6 + 7 = 1 = 1
And there you have it!
*It is important to double check your answer by testing other numbers as well.
