Law = 99 sq.
L = 2w + 7
---
Law = 99
(2w + 7)w = 99
2ww + 7w = 99
2ww + 7w - 99 = 0
---
the above quadratic equation is in standard form, with a=2, b=7, and c=-99
---
to solve the quadratic equation, plug this:
2 7 -99
the roots of the quadratic are:
-9
5.5
---
the negative root doesn't make sense as a length, so use the positive root:
---
w = 5.5
L = 18

Answer:
-10 points
Step-by-step explanation:
A game show awards 30 points for each correct answer and deducts 50 points for each in correct answer. A contestant answers 2 questions incorrectly and 3 questions correctly. What is his final score?
Let us say Initial number of points = 0
Hence,
He answers 2 incorrectly = 0 - 50 - 50
= -100
He answers 3 correctly =-100 + 30 + 30 + 30
His final score = -100 + 30 + 30 + 30
= -10 points
Answer: Chances of cancellation came from a supermarket is given by
![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Explanation:
Since we have given that
Number of supermarkets are there = 6
Number of restaurants are there = 2
According to question,
if one of them called to cancel an order,
so, probability that the cancellation came from a supermarket is given by
Hence,
Chances of cancellation came from a supermarket is given by
![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
