The longest side of a triangle is two times the shortest side, while the medium side is 3 meters more than the shortest side. Th

mylen [45]

Let $s,\ m\, l$ be the short, medium and long side, respectively. If we translate all the information into formulas, we get the following system:

$\begin{cases} l = 2s\\ m=s+3\\ s+m+l = 27 \end{cases}$

Using the second equation, we can express the middle side in terms of the small one, and reduce the system to two equations in two unknowns:

$\begin{cases} l = 2s\\ s+(s+3)+l = 27 \end{cases}$

And thus

$\begin{cases} l = 2s\\2s+l = 24 \end{cases}$

But then again, using the first equation, the third becomes

$2s+l = 24 \iff l+l = 24 \iff 2l = 24 \iff l=12$

So, the longest side is 12. Since the small is half the long, we have $s = 6$ . Finally, the medium is three more of the small, so we have $m = 6+3 = 9$

What is the sum of (2x4 + 5x3 - 8x2 - x + 10) and (8x4 - 4x3 + x2 - x + 2)?

balu736 [363]

Option D: $10x^4+x^3-7x^2-2x+12$ is the right answer

Step-by-step explanation:

Given polynomials are:

$P_1 : 2x^4+5x^3-8x^2-x+10\\P_2: 8x^4-4x^3+x^2-x+2$

We have to find the sum of polynomials

So,

$S = P_1+P_2\\= (2x^4+5x^3-8x^2-x+10) + (8x^4-4x^3+x^2-x+2)\\=2x^4+5x^3-8x^2-x+10+8x^4-4x^3+x^2-x+2\\$

Combining like terms

$=2x^2+8x^4+5x^2-4x^3-8x^2+x^2-x-x+10+2\\= 10x^4+x^3-7x^2-2x+12$

Hence,

Option D: $10x^4+x^3-7x^2-2x+12$ is the right answer
