I need help please! I need to know what is/how to get a,b, and c for factoring trinomials of the problem (x-3)(x+4)=0.

1 answer:

6 0

Answer: Trinomials often (but not always!) have the form x2 + bx + c. ... So, how do you get from 6x2 + 2x – 20 to (2x + 4)(3x −5)? Let's take a look. Factoring Trinomials

Write an equation of the line with the given slope, m and y intercept (0,b) m=-6, b =-1/2 plss

Arlecino [84]

Recall that an equation in slope-intercept form is as follows:

$y=mx+b,$

where m is the slope of the line, and (0,b) is the y-intercept.

Substituting m=-6, and b=-1/2 we get:

$y=-6x+(-\frac{1}{2})\text{.}$

Simplifying the above result we get:

$y=-6x-\frac{1}{2}\text{.}$

Answer:

$y=-6x-\frac{1}{2}\text{.}$

What is the value of x? A.39 B.41 C.26 D.17

mojhsa [17]

Answer:

The answer is B.

Step-by-step explanation:

You have to use Pythogorean Theorem, c² = a² + b² where c is the hypotenuse and a,b is the side lengths :

${c}^{2} = {a}^{2} + {b}^{2}$

Let a = 40,

Let b = 9,

${c}^{2} = {40}^{2} + {9}^{2}$

${c}^{2} = 1600 + 81$

${c}^{2} = 1681$

$c = \sqrt{1681}$

$c = 41 \: units$

*Take note, hypotenuse will always be the longest length among the 3 lengths.

*Pythogorean Theorem can only applied in a right-angle triangle.
