Answer:
I will help you what question
The correct question is
<span>The product of two consecutive positive integers is
11 more than their sum. find the integers.
Let
x-------> the first </span>positive integer
x+1-----> the second consecutive positive integer
we know that
x*(x+1)=11+(x+(x+1))----> x²+x=11+(2x+1)----> x²+x=2x+12
x²-x-12=0
using a graph tool------> to resolve the second order equation
see the attached figure
the solution is
x=4
therefore
the numbers are
x=4
x+1=5
the answer isthe numbers are 4 and 5
The rate of
Glenn in finishing a job would be equivalent to:
Rate (G) = 1
job / 20 minutes
While the
rate of Veronika is:
<span>Rate (V) = 1
job / x ---> x is the
unknown</span>
Where 1 job
for Glenn means completely cleaning his room while 1 job for Veronika means
pulling out everything. Therefore the equation to use would be:
1 / 20 – 1 /
x = 1 / 60
The rate of
Veronika is subtracted from the rate of Glenn since Veronika is slowing Glenn
down. Solving for x:
Multiply both
sides by 60 x
(1 / 20 – 1 /
x = 1 / 60) * 60 x
3 x – 60 = x
2 x = 60
x = 30
<span>Therefore it
takes 30 minutes for Veronika to pull everything out.</span>
