Step-by-step explanation:
10x + 12y is the correct answer
Factored: -(5x+4)(x-1)
Simplified: -5x^2+x+4
Hello,
To solve this question, a good method to use is creating an equation.
The number x being multiplied by 4 can be represented as 4x.
If this results in 25, we can create the equation:
4x = 25
To solve for x, you want to remove the coefficient of 4 from x, so we can divide by 4 on both sides (doing this we will only get x on the left side of the equation, which is what we are trying to solve for).
So, dividing by 4 on both sides, we have
(4x / 4) = (25 / 4)
x = 25/4
x = 25/4, which cannot be further simplified as a fraction. However, this can be represented by 6.25 in decimal form.
x = 25/4, or 6.25

Considering the direction of the wind, it is found that the jet travels faster than the sound during it's journey.
<h3>What is the ground speed?</h3>
The jet's speed, considering that there is a tailwind, is given by:
J = Plane speed + Wind speed.
In this problem, we have that the speeds are given as follows:
Hence the jet's speed is given by:
J = 550 + 120 = 670 knots.
670 knots > 661 knots, hence the jet travels faster than the sound during it's journey.
A similar problem, involving plane and wind's speed, is given at brainly.com/question/25547425

Answer:
Pi is an irrational number
Step-by-step explanation:
Pi is an irrational number, meaning it is a real number that cannot be stated as a fraction. That's because pi is a "infinite decimal," meaning the digits go on forever and ever after the decimal point.
Hope this helps! Have a great day!
