Multiply and simplify out theese brackets(X+1)(x+3)
Lorico [155]
The method in which you do this problem would be to FOIL. First Outer Inner Last. You take the first terms and multiply them. x*x = x^2 (x to the second power). Then you do it with the rest of foil.
x*x = x^2
x*1 = x
x*3 = 3x
1*3 = 3
x^2 + x + 3x + 3 = X^2 + 4x + 3

3 1/4 plus 2 3/4 help me plz
Ilya [14]
The answer would be 6 because by adding the whole numbers, 3+2, you would get 5 and since the fractions both have denominators of 4, you had both fractions, 1/4+3/4, which gives you 4/4 or 1 whole. 5+1=6 and that's your answer.
Hope I Helped!

Solve this system of equations by using substitution<br><br> 3x + 5y = 23<br> y= x + 3
Iteru [2.4K]

Answer:

x=1

y=4

(1,4)

Step-by-step explanation:

TO SOLVE FOR X:

1. Substitute y=x+3 into the equation. This should look like this:

3x+5(x+3)=23

2. Use the distributive property.

3x+5x+15=23

3. Simplify:

8x+15=23

4. Subtract 15 from both sides. It should now lool like this:

8x=8

5. Divide both sides by 8.

x=1

TO SOLVE FOR Y:

1. Take x and substitute into original statement:

3(1)+5y=23

2. Simplify:

3+5y=23

3. Subtract 3 from both sides:

5y=20

4: Simplify:

y=4

CHECK ANSWER:

y=x+3

1. Substitute your answers

4=1+3

2. Simplify

4=4

3. Check for Truth. Is 4=4?

Yes. So your final answer is:

x=1

y=4

(1,4)
