PLEASE PLEASE PLEASE TELL ME HELP HELP
grin007 [14]

Answer:

78%

Step-by-step explanation:

Ok to solve this we can write this as

80 = \frac{73+82+85+83+x}{5}

We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%

Your grade is the average of all of your scores hence the divided by 5

We next multiply both sides of the equation by 5 to get

400 = 72+82+85+83+x

400=  322+ x

78 = x

He must get a 78% minimum on his next test to get 80%

Hope that helps!

Factor the trinomial below. x^2 + 5x – 24 A. (x – 8)(x + 3) B. (x – 4)(x + 6) C. (x – 3)(x + 8) D. (x – 6)(x + 4)
abruzzese [7]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

x² + 5x - 24

To factorize first write 5x as a difference so that when subtracted will give you 5 and when multiplied will give you - 24

That's

x² + 8x - 3x - 24

Factorize x out

That's

x( x + 8) - 3(x + 8)

Factor x + 8 out

We have the final answer as

<h3>(x + 8)(x - 3)</h3>

Hope this helps you
