Hello from MrBillDoesMath!
Answer:
See Discussion section below
Discussion:
2x^2 + 5x + 3 = (2x+3)(x+1) which is Choice 3
3x^2+10x+4 =-1/3 (-3 x + sqrt(13) - 5) (3 x + sqrt(13) + 5)
I don't think any of the provided choices are right!
8x^2+10x-3 = (2x+3)(4x-1) which is Choice 2
6x^2-7x-4 = -1/24 (-12 x + sqrt(145) + 7) (12 x + sqrt(145) - 7)
I don't think any of the provided choices are right!
2x^2+x-28 = (2x-7)(x+4) which is Choice 2
Thank you,
MrB
90% = 72 questions
\\Find 1%
1 % = 72 ÷ 90 = 0.8
\\Find 100%
100% = 0.8 x 100 = 80 questions
Answer: There were 80 questions
Same thing (0, -6) if I’m not mistaken
24 because the ratio is 5:8 and you have to multiply 5 by 3 to get 15
so you have to do the same thing to 8 and multiply it by 3 to get 24

Answer:
3000 ft³
Step-by-step explanation:
The area of a rectangle is:
Height x length x width
So simply plug the given values in:
20 x 15 x 10 = 3000
<h3>So the volume is 3000 ft³</h3>
