4,800 that’s the answer for your equation
Perimeter: P=24 ftLenght: LWidth: W
The length is 2 ft longer than the width:(1) L= W+2 ft
Perimeter: P=2(W+L)P=24 ft2(W+L)=24 ftDividing both sides of the equation by 2:2(W+L)/2 =(24 ft)/2(2) W+L=12 ft
We have a system of 2 equations and 2 unkowns:(1) L=W+2(2) W+L=12
Using the method of substitution: Replacing L by W+2 in the second equation:(2) W+L=12W+(W+2)=12W+W+2=122W+2=12
Solving foe W2W+2-2=12-22W=10Dividing both sides of the equation by 2:2W/2=10/2W=5
Replacing W by 5 in the first equation:(1) L=W+2L=5+2L=7
Answers:What is the width? 5 ftWhat is the length? 7 ft
Answer:
-x² + 2x + 8
Step-by-step explanation:
Essentially we need to subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x) = (2x + 1) - (x² - 7)
Distribute the negative:
(2x + 1) - x² - (-7) = (2x + 1) - x² + 7
Combine like terms:
2x + 1 - x² + 7
-x² + 2x + 8
Thus, the answer is -x² + 2x + 8.

Let's assume x be the number.
Given that, one number is twice the other number. Hence, the second number be 2x.
So, x= smaller number and 2x= larger number.
Given that, difference of x and half of 2x is 20. Hence,
x-x=20 (By simplifying)
0=20
From the above result we can see that x has vanish and we are left with 0=20 which is mathematically not correct.
Hence, there is no solution.
Step-by-step explanation:
x2 - x - 6 = 0
x2 - 3x + 2x - 6 = 0
x(x - 3) + 2(x - 3) = 0
x - 3 = 0. x + 2 = 0
x = 3 x = - 2
Option no 2 and 5 are the correct answer
