Answer:
The width of the football field is 160 feet.
The length of the football field is 360 feet.
Step-by-step explanation:
Let w represent width of the football field.
We have been given that the length is 200 ft more than the width, so the length of the field would be 
.
We are also told that the perimeter is 1,040 ft. We know that football field is in form of rectangle, so perimeter of field would be 1 times the sum of length and width. We can represent this information in an equation as:
Let us solve for w.
Therefore, the width of the football field is 160 feet.
Upon substituting in expression , we will get length of field as:
Therefore, the length of the football field is 360 feet.
You got divide só see mean, the middle number is the median, range you add all number and divide but how many number has
Answer: x = 29.
Step-by-step explanation: Step 1: Simplify both sides of the equation.
x−6=23
Step 2: Add 6 to both sides.
x−6+6=23+6
x=29
Consider marking this answer as brainliest if it helped.
Assuming that the equation is 3x^2+3x-6=0, then use the quadratic equation, (-b+- sqrt(b^2-4ac))/2a, with ax^2+bx+c as the original equation. so here we get (-3+-sqrt(9+72))/6 = (-3+-sqrt(81))/6 = (-3+-9)/6, = (-1+-3)/2 = 1 or -2. Plug in original to check.
8 x 12=96cm^2
Double 96 = 192cm^2
8+4=12
12+4=16
16 x 12=192cm^2
Increase is 4cm
