The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
Answer:
rachel is 10
Step-by-step explanation:
45/3=15
15-5=10
For the first question which is y=x/3, here as we see that both are in top. So they represents direct variation and constant of variation is 1/3 .
For the second question , which is 6/y=x, y is denominator and x is in the denominator. So they represents inverse variation and the constant of proportionality is 6 here .
