A + m = 54, m = a + 4 and, a + m = 54, - a + m = 4,
Combine the equations: 2m = 58
Now solve: 2m = 58, 2m/2 = 58/2, m = 29, therefore a = 24
Answer:
9 :)
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
X=-7 divide both side by 3. Any expression divided by itself equals 1. Dividing a positive and a negative equals a negative. Calculate the quotation. Then you get X=-7
