7) If AB = 3x - 8 and BC = x + 12, find the value of x.​

Answers

Answer 1

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

In a square ABCD, if AB = (3x-8) and BC = (x+12), find the value of x. Also, find the length of each side of the square.

Note that all sides of a square are equal. Hence AB = BC for the square ABCD.

Given AB = (3x-8) and BC = (x+12), then AB = BC

3x-8 = x+12

collect like terms;

3x-x = 12+8

2x = 20

x = 20/2

x = 10

Substitute x = 10 into any of the side. Using side AB

AB = 3x-8

AB = 3(10)-8

AB = 30-8

AB = 22

BC = x+12

BC = 10+12

BC = 22

Hence x = 10 and the length of each side is 22

What is Logarithm?

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the logarithmic equation be represented as A

Now , the value of A is

log₆ 18 = x

From the properties of logarithm , we get

log Aⁿ = n log A

On simplifying , we get

6ˣ = 18

where the value of x = 1.61314

Hence , the exponential equation is 6ˣ = 18

An elm tree is 3 and one-half times as tall as an apple tree. The apple tree is 10 and two-thirds feet tall. How tall is the elm tree?

Answers

Answer:

The elm tree is 40 5/6 inches tall

Step-by-step explanation:

Let

Tallness of the apple tree = x

Tallness of the elm tree= 3 1/2x

Apple tree = 10 2/3 feet tall

Elm tree = 3 1/2x

Where x= 10 2/3

Elm = 3 1/2 (10 2/3)

= 7/2(35/3)

= 7*35 / 2*3

= 245 / 6

= 40 5/6 inches tall

Answers

Answer:

See below.

Step-by-step explanation:

Refer to the graph.

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values is all values greater than or equal to 0.

Therefore, our range is, in interval notation:

[tex][0,\infty)[/tex]

Note that we use brackets with the 0 because 0 is included in our range.

In set notation, this is:

Answers

Answer:

[tex]g[/tex] = 22.5°

[tex]f[/tex] = 67.5°

Step-by-step explanation:

Let’s create a system of equations for [tex]f[/tex] and [tex]g[/tex].

Complementary angles are two angles that add up to 90°, so [tex]f+g=90[/tex]

Also, [tex]f[/tex] is thrice of g: [tex]f=3g[/tex]

We can now substitute [tex]3g[/tex] in [tex]f+g=90[/tex] for [tex]f[/tex].

[tex]3g + g = 90\\\\4g = 90\\\\g=22.5[/tex]

Now, we can find [tex]f[/tex] by substituting [tex]g[/tex] into either equation.

[tex]f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5[/tex]
