Simplify (3x2 − 2) + (5x2 + 5x − 1). (2 points) 8x2 + 5x − 3 8x2 + 5x − 1 2x2 + 5x − 3 8x2 + 7x − 1

D

Step-by-step explanation:

well the anser has to equal 9 if you solved the question correctly BUT the other questions have to equal 9 so the first one is like this

(3*2-2)+(5*2+5*-1)

= (6-2)+(5*2+5*-1)

= (4)+(5*2+5*-1)

= 4+(5*2+5*-1)

= 4+(10+5*-1)

= 4+(10+-5)

= 4+(10-5)

= 4+(5)

= 4+5

= 9

Now the answers A is not it because

8*2+5*-3

= 16+5*-3

= 16+-15

= 16-15

= 1

B isnt it because

8*2+5*-1

= 16+5*-1

= 16+-5

= 16-5

= 11

And C isnt it because

2*2+5*-3

= 4+5*-3

= 4+-15

= 4-15

= -11

So that leaves D and this is how it is correct

= 8*2+7*-1

= 16+7*-1

= 16+-7

= 16-7

= 9

Hope this helps! Sorry I took so long
