Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one
Answer: im stuck on the same one
Step-by-step explanation:
Temperature throughout the year in degrees Fahrenheit. Time in months).
Notice how it gets higher in the middle; like how it gets hotter in the middle of the year. And lower towards the end; as it gets colder in the end of the year.
Also, the time goes to about 12, which works with 12 months

Answer:
The graph is shown below.
Step-by-step explanation:
Given:
Equation of a line is
The equation of a line with a point and slope is given as:
On comparing the given equation with the standard form, we get
Now, we first plot the point .
Slope is . This means that we have to move 3 units down and 5 units right to get the slope as negative. We mark the second point there.
Now, we plot a line joining both the points. Thus, the graph is drawn.
