You can actually do it either way, you could distribute first and then combine, you would get the same answer. I guess it just depends on what you find easier. Here is how to solve it both ways:
Combining First:
8(5x+9x+6)=160
8(14x+6)=160
112x+48=160
112x=112
x=1
NOT Combining First:
8(5x+9x+6)=160
40x+72x+48=160
112x+48=160
112x=112
x=1
so, you would get the same answer both ways, it is of personal preference what you do first.
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab +b²
a = y & b = 10
(y + 10)² = y² + 2 *y*10 + (10)²
= y² + 20y + 100
Answer:
The answer will be the last one which means that will 2
Step-by-step explanation:
You need to find
(f.g)=2 or (f.g) (-2)=2
the answer is 4 because 16 and 20 can both be divided by 4.
