Answer:

x = -6

Step-by-step explanation:

To solve for this, we need to use the basic rules of algebra.

The first thing we need to do is isolate x. Basically, get all the numbers to one side and all the x's to the other.

We need to move the -14 from the left side.

To do this, we can use the addition property of equality to add 14 to both sides.

This gives us -2x = 12

Now that x is alone, we need to remove its coefficient. Let's use the division property of equality to do this. x's coefficient is -2, so we need to divide both sides of the equation by -2. This gives us...

Answer:

x= -6

Step-by-step explanation:

-2x-14=-2

We move all terms to the left:

-2x-14-(-2)=0

We add all the numbers together, and all the variables

-2x-12=0

We move all terms containing x to the left, all other terms to the right

-2x=12

x=12/-2

x=-6

In △ACD, if AC ≅ AD, m∠A = (3x – 4)°, m∠C = (5x + 1)°, and m∠D = (7x – 27)°, find x and the measure of each angle. *

Tems11 [23]

Answer:

x = 14

A = 38

B = 71

C = 71

Step-by-step explanation:

Since we have a triangle, the addition of the measure of all the measure of the angles give 180

Thus;

3x-4 + 5x + 1 + 7x-27 = 180

15x-30 = 180

15x = 180 + 30

15x = 210

x = 210/15

x = 14

To get the measure of each of the angles, we substitute for x

A = 3x-4 = 3(14) - 4 = 38

B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71

C = 7x - 27 = 7(14) - 27 = 98-27 = 71

You are standing on a small fire tower 50 feet from a tree. You notice a squirrel in the tree. You measure the angle of depressi

irina [24]

Answer:

44.81 feet

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ACD

Find the length side AC (height of the small fire tower)

$tan(52^o)=\frac{AC}{50}$ ---> by TOA (opposite side divided by the adjacent side)

Solve for AC

$AC=tan(52^o){50}$

$AC=64\ ft$

step 2

In the right triangle ABE

Find the length side AB

$tan(21^o)=\frac{AB}{50}$ ---> by TOA (opposite side divided by the adjacent side)

solve for AB

$AB=tan(21^o){50}$

$AB=19.19\ ft$

step 3

How many feet off the ground is the squirrel?

Subtract the length side segment AB from the length side segment AC

$64-19.19=44.81\ ft$

A construction worker is tasked with tiling two square rooms, room A and room B. Room B has side lengths that are double the sid

swat32

Answer:

<u><em>4 boxes of tiles.</em></u>

Step-by-step explanation:

Both rooms are square, so each has equal sides. Let's set a side to room A as x. It's area would be x^2. Room B has sides = 2x, so it's area would be (2x)^2 or 4x^2. The ratio of the areas B/A = 4x^2/x^2. B/A = 4.

Room B has 4 times the area of A. If one box of tile completes Room A, Room B would need four times that amount, or 4 boxes.
