BI This year sucks and all but it wouldn’t be that bad if everyone just made themselves some bear shaped pancakes
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

Answer:
The number of sunny days this year = 0.75x
where, x is the sunny days in last years.
Step-by-step explanation:
Given - This year there was 25% fewer sunny days than last year.
To find - What is the number of sunny days this year?
Proof -
Let us assume that,
The total number of sunny days last year = x
Given that,
This year there was 25% fewer sunny days than last year.
i.e this year total sunny days = 100 - 25 = 75 %
So,
we get
If there were x sunny days last year,
Then,
This year Total sunny days = 0.75x
