3(x + 7)2 + 8 = 440 using square roots

Mathematics
1 answer:
ziro4ka [17]3 years ago
7 0
X= 65
Explanation:
Simplify both sides of equations
3(x)+7)(2)+8=440
6x+42+8=440 (Distribute)
(6x)+(42+8)=440
(Combine Like Terms)

Step 2: subtract 50 from each side
6x+50−50=440-50 6x=390

Step 3: Divide both sides by 6
6x/6 = 390/6

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

Find the value of x HELP PLS
Ludmilka [50]

Answer:

x= 36

Step-by-step explanation:

both angles together are supplementary and will form 180

Therefore, you know the missing angle can be found by substracting 108 from 180

180 - 108 = 72

72 = 2x

A right triangle is shown.
jarptica [38.1K]

Answer:

Step-by-step explanation:

From the given right angle triangle,

The unknown side represents the hypotenuse of the right angle triangle.

With m∠x as the reference angle,

the adjacent side of the right angle triangle is 7.8

the opposite side of the right angle triangle is 8

To determine m∠x, we would apply

the Tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan x = 8/7.8 = 1.026

x = Tan^-1(1.026)

x = 45.7° to the nearest tenth
