Answer:

Step-by-step explanation:

did u ever hear of the FOIL method ?

First, outside, inside, last

(5x + 2)(x + 1)

FIRST: multiply the first terms in each set : 5x * x = 5x^2

OUTSIDE: multiply outside terms in each set : 5x * 1 = 5x

INSIDE:multiply inside terms in each set: 2 * x = 2x

LAST: multiply last terms in each set: 2 * 1 = 2

so we now have : 5x^2 + 5x + 2x + 2....combine like terms

5x^2 + 7x + 2 <== ur answer

Suppose a triangle has 2 sides of length 3 and 4 and that the angle between these two sides is 60 degrees. what is the length of

shusha [124]

Answer:

$\boxed{b.\:\:\:\sqrt{13}}$

Step-by-step explanation:

Let the third side of the triangle be $h\: units$ .

We can apply the cosine rule to find $h$ .

$h^2=3^2+4^2-2(3)(4)\cos(60\degree)$

We evaluate to obtain;

$\Rightarrow h^2=9+16-24(\frac{1}{2})$

$\Rightarrow h^2=25-12$

$\Rightarrow h^2=13$

We take the positive square root of both sides to obtain;

$\Rightarrow h=\sqrt{13}$

The correct answer is B.
