The answer is C. Just took the quiz and B was wrong. It needs to be the one with the smaller 12.
<span>Here let the quadratic equation be ax^2 + bx + c
We know that a=5 from the question.
Since the roots are 6 and 2, the quadratic equation would take the form of a product like (a1x-b1)(a2x-b2).
However, let's assume that a2=1 and b2=6,
Since a=5, a1=5, then 5x-b1=5(x-2). Solving this shows that b1=10
So, the equation is (5x-10)(x-6)</span>
Answer:
10. 27 shoes
11. No, both are 18, they are equal
12. 96 dogs
13. 125 students
14. 600 students
15. 50 tulips
16. 70 cars
17. Rory divided the percentage by the number (#/%=#)
Step-by-step explanation:
To find a percentage of somethin, multiply the number by the percent
(54 shoes x 50% (0.50) = 27 shoes)
To find the original number, divide the new number by the percentage
(25 students/20% (0.20) = 125 students)
5⁰ = 1
5¹ = 5
5² = 25
5³ = 125
5⁴ = 625
5⁵ = 3125
