Answer:
D
Step-by-step explanation:
Given a polynomial f(x) with roots say x = a and x = b, then the factors are
(x - a) and (x - b) and f(x) is the product of the roots, that is
f(x) = (x - a)(x - b)
Here the roots are x = - 4, x = 0 and double root at x = 7
Thus factors are (x - (- 4)), (x - 0), that is (x + 4) and x
Given a double root at x = 7 the factor is (x - 7)², thus polynomial is
y = x(x + 4)(x - 7)² → D
Step-by-step explanation:
2.9 hours = 174mins
174 mins = 4.9miles
1 miles = 1740/49 mins
8.73 miles = 310.0mins (1dp)

<u>Answer:</u>
- The numerator '9's share is 450 and the denominator '7's share is 350.
<u>Step-by-step explanation:</u>
<u>Step-1: Add the ratios:</u>
<u>Step-2: Divide 800 by the sum of the ratios:</u>
<u>Step-3: Multiply 50 with each ratio:</u>
Hence, <u>the numerator '9's share is 450 and the denominator '7's share is 350.</u>

Answer:
No it does not.
Explanation:
If you plug in (6,2) into the equation it will become false
y = x - -4
2 = 6-(-4)
2 = 6 + 4
2 = 10
So the answer is no it does not.
