The expressions are simplified and factored in as below.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The expressions are simplified as,
1.
5x + 3x
= 8x
2.
2x + x
= 3x
3.
6x + 8x

= 11x
6.
10x + x
= 11x
7.
3x + 2 + 4x
= 7x + 2
8.
15x + 3 + x
= 16x + 3
9.
2x + 5 + 6x
= 8x + 5
10.
7x + 2x + 4
= 9x + 42
11.
18x + 3x + 9
= 21x + 9
12.
6x + x + 8
= 7x + 8
13.
21x + 15y
= 3(7x + 5y)
14.
2x + 14y
= 2(x + 7y)
15.
15x + 10y

solve x^2-3x+1=0 using completing the square method
This won't be the easiest way to do this problem but as your teacher requires it I will do it that way. But at the end I will show another way to do it with the quadratic formula.
First complete the square
x^2-3x+1=0
(x^2-3x+9/4)+1=9/4
(x-3/2)^2=9/4-1
(x-3/2)^2=5/4
x-3/2=±[tex]\sqrt{\frac{5}{4}[/tex]
x= 3/2±[tex]\frac{\sqrt5}{2}[/tex]
Done!
*Now this next way is not the way your teacher wants you to do it but I personally think its easier.
Just use the quadratic formula x=[-b±sqrt(b^2-4ac)]/2
x=[3±sqrt(9-4*1*1)]/2
x=(3±sqrt5)/2
x=3/2±sqrt5/2
We get the same answer but I think this way is easier. Now if your teacher ask for the top way just do the top way don't do the bottom because you will lose points, its just a shorter way to do things. Now I hope this helped and any additional questions about this just ask me in the comments.

Can I have some help with this? Construct a linear function that has a slope of -3 and passes through the point (-2,3).
Answer:
-3x-3
Step-by-step explanation:
We want our equation to look like this
y=mx+b
we know that m= -3 so we just need to find b
We can start by plugging in the ordered coordinates into our equation
3=(-3)(-2)+b
Solve for b
3=6+b
b= -3
Which means our final equation is
y= -3x-3
x intercept of y = -3x + 3

Step-by-step explanation:
Jayden is driving 390 miles to visit the Gateway Arch in St. Louis. He drives at an average rate of 65 miles per hour. Explain how you can find the amount of time it will take her to get to the arch
Using the relation between velocity, distance and time, it is found that it will take her 6 hours to get to the arch.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
For this problem, we have that:
She drives 390 miles, hence d = 390.Her velocity is of 65 miles per hour, hence v = 65.We can solve the equation for t to find the time, hence:
65 = 390/t
65t = 390
t = 390/65
t = 6.
It will take her 6 hours to get to the arch.
