Step-by-step explanation:

Given

(2x + 3 )² - (2x + 3) (x - 5)

= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))

= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )

= 4x² + 6x + 9 - 2x² + 10x - 3x + 15

= 2x² + 13x + 24

Hope it will help :)

How many solutions does the system have?
amid [387]

Answer:

A; infinitely many solutions

Step-by-step explanation:

first, let's simplify the first equation to make it simpler.

divide both sides by 5

y=3x-8

new system

y=3x-8

y=3x-8

as you can see, they are the same.

not mandatory but useful!⬇⬇⬇⬇

just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.

3x-8=3x-8

add 8 to both sides; subtract 3x from one side

0=0

the answer is A, Infinitely many solutions.

hope this helped <3333333
