13 11/28 hope that helps :)
(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:
-1
Step-by-step explanation:
If a straight line passes through the known points (x1, y1) and (x2, y2), the its slope is given by
Now, in our case the straight line passes through the points (1.8, - 3.4) and (6.8, - 8.4).
Therefore, the slope of the required straight line will be
