This is an equation representing the ellipse
Explanation:
- The general equation for an ellipse is
so, when you simplify it according to the characteristics of a and b, you would end up in the similar form of the equation given
- where a represents half the length of the major axis and b represents half the length of the minor axis.
- The easiest method to identify, look at whether both the variables are squared, and also the coefficient of x and y should be positive but different.
Answer:
it depends... is it a scrawny middle schooler? is the man a bodybuilder? is the man short? are the other men strong or fast at the job? if so it changes all variables...

Answer:
if you are going 5 miles pr hour how many feet csn u walk
Step-by-step explanation:
the answer is we doont know
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
