Answer:

6x^2 + 2x - 5 (Option C)

Step-by-step explanation:

1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.

2. Second, add -5x and 7x (which is 2x)

3. Lastly, subtract 3 and 8, which is -5

WHY DOES THE ANSWER HAVE A NEGATIVE 5?

The equation looks like this: +3 + -8

You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)

Answer:

C. 6x^2 + 2x - 5

Step-by-step explanation:

-5x + 7x = 2x

3 - 8 = -5

Therefore,

4x^2-5x+3 + 2x^2+7x-8 = 6x^2+2x-5

I'm a little bit confused about how to approach this can someone help?
Taya2010 [7]

Answer:

4

Step-by-step explanation:

ΔABC is congruent with ΔDEF.  That means the corresponding sides are congruent.

Look at the order of the letters.  EF are the last two letters of ΔDEF.  So this corresponds with the last two letters of ΔABC.  Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.
