Answer:
Option 2 is correct.
Step-by-step explanation:
Given the expression 5x(x + 3) + 6(x + 3).
We have to factorize the expression completely.
Expression is
5x(x + 3) + 6(x + 3)
Take the factor (x+3) common from both the terms, we get
(x+3)(5x+6)
Hence, option 2 is correct.

As you requested, I'll proceed now to solve your equation for 'x'.
I'll go slowly, and explain each step clearly. Please try to follow
along with my procedure.
Step #1:
Write down the equation: 52 x = 7,800 y
Step #2:
Divide each side of the equation by 52 : x = 7,800 y / 52
Step #3:
Perform the division indicated by the fraction, and underline the answer.
x = 150 y

I'm sure you know how to find the slope of a line if you know 2 points
on it ... The slope is ...
(difference in y-values) / (difference in x-values) .
Right ?
OK. Each line in these tables is a point on the graph of the table.
Pick two points from the table, and you can get the slope of the line
from them.
The first table (Plan-A) has these points in it:
1 . . . . . $20.15
2 . . . . . $20.30
3 . . . . . $20.45
4 . . . . . $20.60
You want to find the equation of the line with these 4 points on it.
That means you need to find the slope and the intercept of the line.
Take any two points straight from the table. I'll use the first two:
1 . . . . . $20.15
2 . . . . . $20.30
There you have two points on the line: (1, 20.15) and (2, 20.30) .
The slope is (difference in 'y') / (difference in 'x').
Difference in 'y' = (20.30 - 20.15) = 0.15
Difference in 'x' = (2 - 1) = 1
Slope of the line = (0.15) / 1 = 0.15
(What that really means is 15 cents per minute on Plan-A.)
Now you know that the equation of the line is [ y = 0.15x + intercept ].
Can you think of a way to find the intercept ?
Remember ... every point in the table is on the line.
So why not just take one of these points in the table, put it into the part of the equation that you already have, and watch the intercept fall out ?
You could use any point at all from the table.
I'll use the 3rd one.
y = 0.15x + intercept
20.45 = 0.15(3) + intercept
20.45 = 0.45 + intercept
Subtract 0.45 from each side: 20.00 = intercept
The equation of the graph for Plan-A is Charge = 0.15(minutes) + $20.00
===============================
Plan-B:
First two points:
Difference in y-values = (8.00 - 6.50) = 1.50
Difference in x-values = (10 - 5) = 5
Slope of the line = (1.50) / (5) = .30 (30 cents per minute)
Intercept = 5.00
Charge = 0.3(minutes) + $5.00
======================================
Plan-C:
Slope = 4.50 / 10 = 0.45
Intercept = zero
=================================
Plan-D:
Slope = (16.50 - 11.00) / (30 - 20) = 5.5/10 = 0.55
Intercept = zero
In each plan, the intercept is the cost just to sign up, before you use
the phone, and then the slope is the cost for each minute of talking on it.
