5x + y = 27
substitute: 5x + 4x = 27
combine: 9x = 27
divide (by 9): x = 3
Answer:
p = -15
Step-by-step explanation:
-2 = (p+9)/3 multiply both sides by 3 to get rid of fraction
-6 = p + 9 subtract 9 from both sides
-15 = p
I believe that it is B. Hope this helps!
Answer:
The answer is B.)
Step-by-step explanation:
Because, 5 x 2 = 10 and 10 - 3 = 7 .
(x + 5)²z
(x + 5)(x+ 5)z
(x² + 5x + 5x + 25)z
(x² + 10x + 25)z
(x²)z + (10x)z + (25)z
x²z + 10xz + 25z
