38 seedlings
solve 2n + 2 = 78
subtract 2 from both sides
2n = 78 - 2 = 76
divide both sides by 2
n = = 38
number of seedlings that can be planted is 38

for example, let's look at the first set
y+3x =5 or y = -3x+ 5
and y = -3x + 2
y = m + b
the slopes are equal, the y-intercepts differ
that means, they're just parallel lines, no solution
Answer:
Step-by-step explanation:
First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division
Then, you have
Subtract both sides by a squared
DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition
From that you get
Finally, divide both sides by 3.
You get
