Answer:

3.) (x + 5) (x - 6)

Step-by-step explanation:

Factor the following:

x^2 - x - 30

Hint: | Factor x^2 - x - 30 by finding two numbers whose product is -30 and whose sum is -1.

The factors of -30 that sum to -1 are 5 and -6. So, x^2 - x - 30 = (x + 5) (x - 6):

Answer: (x + 5) (x - 6)

A box on a 20 degree incline is shown with vectors radiating from a point in the center of the box. The first vector points up a

Finger [1]

The images to solve this problem is in the attachment.

Answer: $F_{fs}$ = 671.0 N; $F_{N}$ = 300 N

Step-by-step explanation: From the image in the attachment and knowing that the box is in equilibrium, i.e., the "sum" of all the forces is 0, it is possible to conclude that:

$F_{fs}$ = $F_{gx}$ and $F_{N}$ = $F_{gy}$

Using trigonometry, shown in the second attachment, the values for each force are:

Force of Static Friction

sin 20° = $\frac{F_{gx} }{F_{g} }$

$F_{gx}$ = $F_{g}$ . sin(20)

$F_{gx}$ = 735.0.913

$F_{gx}$ = 671.0

Normal Force

cos 20° = $\frac{F_{gy} }{F_{g} }$

$F_{gy}$ = $F_{g}$ . cos (20)

$F_{gy}$ = 735.0.408

$F_{gy}$ = 300

The force of static friction is 671N and normal force is 300N

The hypotenuse can be solved by this formula. X^2 = 6^2 +6^2

X^2=64
Usually you cut it down to 8 but it wants the squared form so 64.
