Answer:
Value of x using quadratic formula (x = -4) and (x = -5)
Step-by-step explanation:
Given:
Equation
x² + 9x + 20 = 0
Find:
Value of x using quadratic formula
Computation:
Quadratic formula = [-b±√b²-4ac] / 2a
Given equation;
x² + 9x + 20 = 0
a = 1 , b = 9 , c = 20
By putting value
[-9±√9²-4(1)(20)] / 2(1)
[-9±√81-80] / 2
[-9±√1] / 2
(-9 + 1) / 2 , (-9 - 1) / 2
-8 / 2 , 10 / 2
-4 , - 5

Answer:
where x denotes number of small rooms and y denotes number of large rooms
Step-by-step explanation:
Given: Small rooms can hold 3 people, and large rooms can hold 4 people.
Number of small rooms is twice the number of large rooms.
Small rooms and large rooms altogether can accommodate 70 guests.
To find: system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved
Solution:
Let x denotes number of small rooms and y denotes number of large rooms.
As number of small rooms is twice the number of large rooms,

As small rooms and large rooms altogether can accommodate 70 guests such that small rooms can hold 3 people, and large rooms can hold 4 people,
