The area of the triangle extension is 12, because the total side length it is on is 18, and the segments to the sides of the triangle are 6 each, meaning 18-12=6, the height of the triangle. The base is given as 4, so 1/2(4x6)=24/2=12.
Add this to the area of the rectangle, 9x18=162, and 162+12=174.
The area is 174.
11-2×48= 412. So the value of the expression is 412.

Answer:
y=3x+4
Step-by-step explanation:
The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

where m=3 is the slope .
We substitute the slope to get:

We substitute the point to find b.

The equation of the straight line is:

Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have

This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k

The unit rate is the same that the slope
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2
