2x+4y=36 legs
2 for the two legged animals and 4 for the four legged animals
There are 10 animals so insert numbers that add up to 10 in for x and y
In this case x=2 y=8
Hope this helps!

Answer:
Domain: x=(0,∞)
Range: f(x)=(-∞,∞)
Step-by-step explanation:
For the domain:
The square root of a number is defined in real numbers only for positive numbers.
For the range:
The square root of a number could be positive or negative with any restriction. For example, 
could be 5 or -5.
Hey there! I'm happy to help!
Step 2 is incorrect. She added 4 and 2 first, but you are supposed to multiply and divide first. Then she multiplied 6 and 6, which is 36. Then she divided 36 and 2, which is 18, and then she subtracted 7, giving her 11. Step 2 is what threw the whole thing off.
Here is what Sandy should have done.
STEP 1: 6·4+2÷2-7
STEP 2: 24+1-7
STEP 3: 25-7
STEP 4: 18
I hope that this helps! Have a wonderful day! :D
Jenna is correct and Billy is wrong because the equation was not converted to a quadratic form.
<h3>Form of quadratic equation</h3>
The form of quadratic equations is given as
ax2 + bx + c = 0
So, for the quadratic equation, we have
x² - x = 12
Let's make it into quadratic form
x² - x - 12 = 0
Bill solved it as
x(x - 1) = 12
This is wrong, because quadratic equations must be written in the form before solving for the variables
Jenna solved it as
x 2 - x - 12 = 0
Jenna is correct because she converted the equation to a quadratic form before solving for the variables.
Thus, Jenna is correct and Billy is wrong because the equation was not converted to a quadratic form.
