We are given
number of heads =15
we know that
any healthy dragon has three heads
horse has 1 head
chicken has 1 head
Let's assume
number of dragons is x
number of horses is y
number of chickens is z
so, we will get
first equation:

number of legs =50
any healthy dragon has four legs
chicken has 2 legs
horse has four legs
so, we can get second equation as

we can simplify it


now, we can find third equation
dragon has two wings
horse has no wings
chicken has two wings
so, we will get third equations as

now, we can simplify it



so, we will get system of equations as



now, we can use substitution
We can find for z from third equation

we can plug this in first equation

now, we can solve for y


now, we can plug this z and y into second equation

now, we can solve for x



now, we can find y and z

we can plug x=1



we can plug x=1


Hence ,
number of dragons is 1
number of horses is 11
number of chicken is 1............Answer
Answer:
No
Step-by-step explanation:
65 is closer to 0 on the number line. Therefore 65 has a lower value the 344.
Hello there,
Well we are given with 3(x + 4)² and we need to simplify this expression...
- write out the expression: 3(x + 4)(x + 4)
- then we distribute the parentese: 3(x² +4x +4x +16)
- combine like terms: 3(x² + 8x + 16)
- distribute the 3 in the parentese: 3x² + 24x + 48
So another way to express this would be 3x² + 24x + 48.
Hope I helped,

A negative number is always less than a positive number.
When comparing two negative numbers, the smaller negative number is the greater value.
The answer would be 5. -5 > -18
I guess you mean the derivative of:
√7x + √2x, if so then:
Remember that the derivative of √u = 1/(2√u) . u'
if 7x = u, then u' = 7 , hence the derivative of √7x is 7/(2√7x)
Use same logic for √2x and you will find:
y' = 7/(2√7x) + x/√2x
