Answer:
I would the answer is x^6+1
Step-by-step explanation: First you add X^2 +x^4=X^6
than you add the 2/3 and the 1/3 which simpflies to 1

The relation between the number thought by Ann (N) and the final result (R) can be expressed as
So if for example, Ann thought in the number N=12, then
If we know the value of R, it's easy to find back the value of N by solving the equation
subtracting 7 on each side
Dividing by 5
So, if Ann tells Jim that R = 52, he can guess her number is
The formula for finding the area of a rug:
Plugging in the values we know, we can solve for s.
Take the square root of both sides.
is approximately equal to 8.89
So, 8.89 feet is the answer.
Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
We will be using simultaneous equations to solve this problem.
Let's establish the two equations we will be using to solve the problem.
Let present age of father = f
Let present age of son = s
Equation No. 1 -
f = 3s
Equation No. 2 -
f + 15 = 2s
To begin with, we will substitute the value of ( f ) from the first equation into the second equation to solve for ( s ).
Equation No. 2 -
f + 15 = 2s
( 3s ) + 15 = 2s
3s - 2s = - 15
s = - 15
Next we will substitute the value of ( s ) from the second equation into the first equation to solve for ( f ).
Equation No. 1 -
f = 3s
f = 3 ( - 15 )
f = - 45
FINAL ANSWER:
Therefore, the present age of the father is - 45 years old.
It isn't possible for someone to be negative years old but this is the answer that I obtained from the equations.
Hope this helps! :)
Have a lovely day! <3
