You probably are interested in expressing the given equation as a quadratic equation in u, as it will make it easy to find the solutions.
Let u = x²
So,
u² = x⁴
So, the given equation can be written as:
u² - 17u + 16 = 0
Now the equation is quadratic in u and the solutions can be calculated using quadratic formula or factorization.
Answer:
42300000
Step-by-step explanation:
Use known fact

Consider 1 square kilometer:

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

Next four multipules of 4/8
to keep the value of 4/8 the same, we must multiply the top number and bottom number by the same thing
4/8 times 2/2=8/16
4/8 times 3/3=12/24
4/8 times 4/4=16/32
4/8 times 5/5=20/40
next 4 multipulees are
8/16, 12/24, 16/32, 20/40
You know that the length is 2 more than the width. If z is the width then y = z(z+2). I don't see the graph so you will have to scan and look for that y-z relationship.
