In a polynomials equation do you add the exponents if they are different
Alexus [3.1K]
You can only add exponents if you are multiplying two of the same variable together. For example,
x^{12} \times x^4 = x^{16}

You take them away if you are dividing.
<span>x^{12} \div x^4 = x^{8}

In a polynomial equation, you can add together two of the same variable if they have the same exponent
</span>3x^4 + 7x^4 = 10x^4

Or you can take them away in a similar fashion,
<span>3x^4 - 7x^4 = -4x^4

But you cannot add two (or more) different exponents,
</span>6+4x+7x^2 = 6+4x+7x^2 (it does not get any simpler)

I hope this has answered your question, if not, leave a comment and I'll update the answer.

A home gardener estimates that 24 apple trees will have an average yield of 104 apples per tree. But because of the size of the
d1i1m1o1n [39]

Answer:

The farmer should plant 14 additional trees, for maximum yield.

Step-by-step explanation:

Given

Trees = 24

Yield = 104

x \to additional\ trees

So, we have:

Trees = 24 + x

Yield = 104 - 2x

Required

The additional trees to be planted for maximum yield

The function is:

f(x) = Trees * Yield

f(x) = (24 + x) * (104 - 2x)

Open bracket

f(x) = 24 * 104 + 104x - 24 * 2x - x * 2x

f(x) = 2796 + 104x - 48x - 2x^2

f(x) = 2796 + 56x - 2x^2

Rewrite as:

f(x) = - 2x^2 + 56x + 2796

Differentiate

f'(x) = -4x + 56

Equate f'(x) = -4x + 56 to 0 and solve for x to get the maximum of x

-4x + 56 = 0

-4x =- 56

Divide by -4

x =14

The farmer should plant 14 additional trees, for maximum yield.

A submarine dives to a depth of 54.6 meters below the surface of the water in 4 minutes. What integer represents the constant ra
Katen [24]
Just divide the depth he dove by the time it took him to dive.

54.6 / 4 = 13.65

So he traveled at a constant rate of 13.65 meters a minute.
