Answer:

(x - 9)(x + 4)

Step-by-step explanation:

x^2−5x−36

As you know, -36 = -9 * 4 and (-9) + 4 = -5

so Factor

= (x - 9)(x + 4)

Answer:

x^2 − 5x − 36 = (x - 9)(x + 4)

Step-by-step explanation:

You need to find two numbers whose product is -36 and whose sum is -5.

-36 = -4 * 9; sum -4 + 9 = 4 wrong sum

-36 = -9 * 4; sum -9 + 4 = -5 right sum

The numbers are -9 and 4.

Answer: x^2 − 5x − 36 = (x - 9)(x + 4)

Answer:

Angle 3 is 49 degrees

=============================

Explanation:

Angle 1 is 50 degrees and angle 2 is 48 degrees. Added up, they total to 98 degrees. This is angle DEF.

Angle DEF is congruent to angle ABC because they are alternate exterior angles and because lines m and n are parallel

We are told that angle ABC is bisected (aka cut in half) because of line s; which means that the angles labeled "4" and "5" are exactly half that of angle ABC = 98 degrees

Therefore, angle 4 is 98/2 = 49 degrees and so is angle 3 (due to angles 3 and 4 being vertical angles; angle 3 = angle 4)

Solve x2 – 4x – 9 = 29 for x.

Irina-Kira [14]

$x^2 - 4x - 9 = 29 \\ x^2 - 4x - 9 - 29 = 0 \\ x^2 - 4x - 38 = 0 \\ x= \frac{-b \pm \sqrt{ b^{2} -4ac} }{2a} 
$ ; where a = 1, b = -4 and c = -38
$x= \frac{-(-4) \pm 
\sqrt{ 
(-4)^{2} -4 \times 1 \times -38} }{2 \times 1} \\ = \frac{4 \pm \sqrt{ 16 +152} }{2} \\ =\frac{4 \pm \sqrt{ 168} }{2} \\ =\frac{4 \pm 
2\sqrt{42} }{2} \\ 
=2+\sqrt{42} \ or \ 2-\sqrt{42}\\=8.48 \ or \ -4.48$
