How to factor 9x^4-6x^2y^4+y^89x4−6x2y4+y8

Mathematics

Virty [35]3 years ago

Answer:

(3x^2-y^4)(3x^2-y^4)

Step-by-step explanation:

We'll assume the correct expression to be factored is

9x^4-6x^2y^4+y^8

One must try to find out if the expression is a perfect square. To test it, we'll take the square root of the first and the last term. If they are exact, we'll procceed with the next step

\sqrt{9x^4}=3x^2

\sqrt{y^8}=y^4

Since both are exact, we'll test if the middle term is twice the product of both square roots:

2(3x^2)(y^4)=6x^2y^4

We confirm the middle term equals the above expression. All tests confirm the original expression is

\left ( 3x^2-y^4 \right )^2

The required factoring is

(3x^2-y^4)(3x^2-y^4)

Cathy borrows $3280 at 0.3% simple interest per month. When Cathy pays the loan back 9 years later, what is the total amount tha
Lisa [10]
Answer:

Step-by-step explanation:
Interest formula -
I = P × R × T
I = 3,280 × 0.3% × 9
What I basically did there wws multiply the amount of money, the simple interest, and the time.
Turn 0.3% into a decimal by dividing by a 100 which should give you 0.003

I = 3,280 × 0.003 × 9

Put that into a calculator, you get $88.56

Now, that's just the interest amount. Now you add it back to 3,280 to get the *total* amount.

3,280 + 88.56 = 3,368.56

Cathy ends us paying $3,368.56

Hope what I said made sense.

In the equation 2y=18, determine which property of equality will be used to isolate the variable. Choose the best answer. A. Mul
mixer [17]

Answer:

(C) Division Property of Equality

Step-by-step explanation:

Looking at the equation 2y=18, we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.

The Division Property of Equality states that if we have an equation, a=b, then a\div c = b\div c.

So, that means 2y\div 2 will be equal to 18 \div 2, which is 9.

Hope this helped!
