Answer:
The answer to the equation is B.
Step-by-step explanation:
Answer:
I believe it is the last choice.
Step-by-step explanation:
Step-by-step explanation:
Monomial = x^2, 1 term
Binomial = x^2 + x, 2 terms
Trinomial = x^2 + x + 3, three terms
Binomial is more than 3 terms
Let's do a 3rd degree polynomial like:
- Now let's put parenthesis around (x^3 + 2x^2) and (4x + 8)
- Let's treat both of these as seperate for now. In the first part, you can see an x^2 can be factored out of it
- As you can see, if you do the distributive property, it equals the original.
Now let's factor the second part, the 4x + 8. This can be factored by a 4.
Your new equation is:
x^2 + 4 can be factored again down to (x + 2)(x + 2)
YOUR FINAL EQUATION IS:
9514 1404 393
Answer:
(c) 14.5 cm
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(65°) = BC/BA
BC = BA·sin(65°) ≈ (16 cm)·0.9063 ≈ 14.501 cm
BC ≈ 14.5 cm

As is often the case, a simple estimate is all that is needed to identify the correct answer choice.
You only need to know how the long side of a right triangle compares to the others. In an isosceles right triangle, both legs are √2/2 ≈ 0.71 times the hypotenuse. The long side of a right triangle will never be shorter than that. This means the long side must be greater than about 11.2, and cannot be greater than 16. There is only one answer choice in that range.
