Can someone please help!!! I really need the answer
Answer:
3x - 2
Step-by-step explanation:
[tex]4x + 2 - \frac{ {x}^{2} + x - 12}{x - 3} \\ \\ = 4x + 2 - \frac{ {x}^{2} + 4x - 3x- 12}{x - 3} \\ \\ = 4x + 2 - \frac{ {x}(x + 4) - 3(x + 4)}{x - 3} \\ \\ = 4x + 2 - \frac{ (x + 4) \cancel{(x- 3)}}{\cancel{(x- 3)}} \\ \\ = 4x + 2 - (x + 4) \\ \\ = 4x + 2 - x - 4 \\ \\ = 4x - x + 2 - 4 \\ \\ = 3x - 2[/tex]

Simplify the following : x^2y^-3 / x^5y^2
Answer:
Step-by-step explanation:
[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}[/tex]
Remember that exponents (or powers) of the same basis can be divided by subtracting the exponents. For example [tex]\frac{x^n}{x^m} =x^{n-m}[/tex]
Using this information, we can easily rearrange our equation to look like this:
[tex]\frac{x^2}{x^5} \frac{y^{-3}}{y^2}[/tex]
Now that the basis are the same, we can conveniently subtract the exponents to get the following result:
[tex]x^{-3}y^{-5}[/tex] or [tex]\frac{1}{x^3y^5}[/tex]. And that's the final answer.

What is the volume of a rectangular jewelry box with the length of 12 cm, a with of 7 cm and the height of 7 cm?
Answer:
588
Step-by-step explanation:
12x7x7=(12x7)x7=84x7=588
Have Fun Lolz! Follow TheLisaAkin On TikTok!
The volume of the rectangular jewellery box will be 588 cubic cm.
Volume is defined as the space occupied by any object in the three dimensions. All three parameters are required for the volume like length, width and height of cube or cubes.
The rectangular box is made up of six surfaces. The area of the two opposite surfaces is always equal.
Given that the dimensions of the rectangular box are a length of 12 cm, a with of 7 cm and a height of 7 cm.
The volume of the rectangular box will be calculated as,
Volume = L x W x H
Volume = 12x7x7=
Volume = (12x7)x7
Volume = 84x7
Volume = 588 cubic cm

Work out length AC.
(my teacher told me to start out with c first, c= an something like that I don’t remember)
Step-by-step explanation:
<c =90 °
So, Pythagoras theorem can be used,
Hypotenuse ² = base ² + altitude ²
AB²=AC²+BC²
11²=AC²+4²
11²-4²=AC²
121-16=AC²
Root 105=AC
AC=10.2 cm
The length of AC is 10.25 cm
What is pythagorean theorem ?
If ΔABC is a right angle triangle, then
AB² = BC²+AC²
where AB = Hypotenuse, BC & AC are adjacent sides of the right angle
What is the required length of the side ?Given, hypotenuse = AB = 11 cm
One of adjacent sides = BC = 4 cm
We have to find the length of AC.
Using pythagorean theorem,
AB² = BC²+AC²
⇒ AC² = AB² - BC²
⇒ AC² = 11²-4²
⇒ AC² = 121-16
⇒ AC = √105
⇒ AC = 10.25
So the length of AC = 10.25 cm

1. Rafael stands 55 feet from the tower and uses a clinometer to measure the angle of elevation to the
viewing platform as 37º. How far up the tower is the viewing platform?
Answer:
41.4feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Given the following
Distance of Rafael from the tower = 55feet = Adjacent
Angle of elevation = 37degrees
Required
Height of the tower = Opposite
Since Tan theta = opp/adj
Tan 37 = x/55
x = 55tan37
x = 55(0.7536)
x = 41.4
Hence the tower is 41.4feet up the viewing platform

What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
a)
Let the first triangle be ΔNQR
QR = 17 m
NQ = 21 m
NR = 24 m
Now , the angle opposite to the side having the largest length will be the largest angle
And , the angle opposite to the side having the smallest length will be the smallest angle
So , substituting the values in the equation , we get
Angle opposite to QR = Angle N
Angle N is the smallest angle in ΔNQR
And , Angle opposite to NR = Angle Q
Angle Q is the largest angle in ΔNQR
Therefore , Angle N < Angle R < Angle Q
b)
Let the second triangle be ΔGHJ
HJ = 6 in
GJ = 7 in
GH = 10 in
Now , the angle opposite to the side having the largest length will be the largest angle
And , the angle opposite to the side having the smallest length will be the smallest angle
So , substituting the values in the equation , we get
Angle opposite to HJ = Angle G
Angle G is the smallest angle
Angle opposite to GH = Angle J
Angle J is the largest angle
Therefore , Angle G < Angle H < Angle J
Hence , the angles are in the order
a) Angle N < Angle R < Angle Q
b) Angle G < Angle H < Angle J

A triangle has a total of 180 degrees. To find the missing angle, we subtract 113 and 32 from 180 to get the answer.
Answer:
h = 35
Step-by-step explanation:
113 + 32 + h = 180
113 + 32 = 145
180 - 145 = 35
