How can you know if this equation is true? 1/2 + 3/8 = 4/10 = 2/5

romanna [79]

Answer:

<h2>2. Because 25<12, this equation can not be true.</h2>

Step-by-step explanation:

I just solved the equation and 1/2 + 3/8 = 7/8 or 87.5%.

4/10 equals 40%.

Since these two do not sync up, the equation must be false and 2 is the only answer saying the equation is false.

I'm always happy to help :)

Which expression is equivalent to -1/12x-1/3?

hichkok12 [17]

B. If you multiply 1/12 by (-x) it's -1/12x and if you multiply 1/12 by (-4) it's -4/12 which is equivalent to -1/3.

For the polynomial 6xy2 – 5x2y? + 9x2 to be a trinomial with a degree of 3 after it has been fully simplified, the missing expon

Karolina [17]

Consider the polynomial $6xy^2-5x^2y^?+9x^2$ .

For this polynomial to be trinomial with a degree of 3. We have to identify the missing exponent of the 'y' term.

Let the missing exponent of the 'y' term be 0

So, the polynomial will be $6xy^2-5x^2y^0+9x^2$

= $6xy^2-5x^2+9x^2$

= $6xy^2+4x^2$ which is not a trinomial, which is a binomial.

So, the missing exponent of 'y' can'not be zero.

Let the missing exponent of the 'y' term be 2

So, the polynomial will be $6xy^2-5x^2y^2+9x^2$

= $6xy^2-5x^2y^2+9x^2$

= $6xy^2-5x^2y^2+9x^2$ which is a trinomial of degree 4.

So, the missing exponent of 'y' can'not be '2'.

If we will take the missing exponent of 'y' more than 2, than the degree of the given polynomial will not be 3 anymore.

Let the missing exponent of the 'y' term be 1

So, the polynomial will be $6xy^2-5x^2y^1+9x^2$

= $6xy^2-5x^2y+9x^2$

= $6xy^2+4x^2$ which is a trinomial of degree 3

So, the missing exponent of 'y' is 1.
