(6a+10)⋅(3a+55)=18a^2+330+30a+550
=18a^2+330a+30a+550=18a^2+360a+550
a=-5/3 or a=-55/3
hope it helps!

Answer:
11/14
Step-by-step explanation:

6/14+5/14 = 11/14
Answer:
0.5 seconds
Step-by-step explanation:
Two rockets are launched at the same time, but from different heights.
when the heights are same then y are equal. So equation both equations and solve for t
Add -16t^2 on both sides
Subtract 150 t from both sides
Divide 10 on both sides
t=0.5 seconds
To solve for m you have to isolate it.
Subtract the b from both sides:
y-b=mx
Divide by x:
(y-b)/x=m
Answer:
m=(y-b)/x
