Answer:

D

Step-by-step explanation:

We know that we are adding the two expressions because the question says "sum" which means that we need to add. Let's combine like terms. We know that x + 2x = 3x and 5 + 3 = 8 so the answer is 3x + 8.

Answer:

D. 3x+8

Step-by-step explanation:

We want to find the sum of (x+5) and (2x+3). Sum means addition, so we must add the 2 expressions.

(x+5)+(2x+3)

Now, we must simplify by combining like terms.

First, combine the terms with variables.

(x+2x) + (5+3)

3x + (5+3)

Next, add the constants, or terms without variables.

3x+ 8

The sum of (x+5) and (2x+3) is 3x+8. This makes choice D the correct answer.

The numbers 45 28 53 form a pythagorean triple true or false
GarryVolchara [31]
You can verify this by plugging the numbers into the Pythagorean theorem, a^2+b^2=c^2, where c is the hypotenuse (the longest side, in this case 53).

So it would be: 28^2 + 45^2 = 53^2
The equation is true.
2809 = 2809
