<h3>Answer:  Choice B</h3>

Consider that choice B is the same as saying 2x^2+1x^0.

The exponents 2 and 0 are both even, which is sufficient to say that the entire polynomial function itself is also even.

Something like choice A expands out and simplifies to x^2-2x+2, and that's equivalent to saying x^2+2x^1+2x^0. The presence of the x^1 term, with its odd exponent, is what makes choice A not even (it's not odd either).

Similarly, choices C and D also have exponents of 1, so they aren't even either.

How many different triangles can you make if you are given these two lengths for sides?
kykrilka [37]

Answer:

Infinitely many triangles.

Step-by-step explanation:

Given the lengths of two sides are 8 inches and 10 inches.

Let's assume third side = x inches.

Using the Triangle Inequalities given as follows:-

1. a+b > c,

2. b+c > a,

3. c+a > b.

Using the lengths given in the problem, we can write:-

1. x+8 > 10 ⇔ x > 10-8 ⇔ x > 2.

2. x+10 > 8 ⇔ x > 8-10 ⇔ x > -2.

3. 8+10 > x ⇔ x < 18.

So, the solution set is 2 < x < 18. It means third side can take any value in interval (2, 18).

Hence, there are infinitely many triangles.

Answer:

-89 +4i sqrt (3)

Step-by-step explanation:

sqrt(-48) - 89

sqrt(-1) sqrt(48) - 89

We know that sqrt(-1) = ±i

±i sqrt(48) - 89

±i sqrt(16)sqrt(3) - 89

±4i sqrt(3) - 89

Taking the principal square root

-89 +4i sqrt (3)
