Solve x2 + 18x – 19 = 0 by completing the square.
Answer:
x = 1, x = -19
Step-by-step explanation:
1) factorise
(x−1)(x+19)=0
2) equal to 0
x−1=0 or x+19=0
x=1 or x=−19
Answer:
[tex]x = 1[/tex]
[tex]x = 19[/tex]
Step-by-step explanation:
Set up equation
[tex] {x}^{2} + 18x - 19 = 0[/tex]
Add 19 on both sides
[tex] {x}^{2} + 18x = 19[/tex]
Divide 18 by 2 and sqr it.
[tex]( \frac{18}{2}) {}^{2} [/tex]
[tex] {9}^{2} = 81[/tex]
Add 81 on both sides
[tex] {x}^{2} + 18x + 81 = 100[/tex]
Using the AC method, isolate the left side into a binomial.
[tex](x + a)(x + b)[/tex]
that a and b can be added to equal 18 and be multiplied to equal 81.
Only number that does that is 9. 9+9=18, 9×9=81
[tex](x + 9)(x + 9)[/tex]
[tex](x + 9) {}^{2} [/tex]
Set up equation
[tex](x + 9) {}^{2} = 100[/tex]
Take sqr root of both sides
[tex]x + 9 = 10[/tex]
Since sqr root of a positve number can be negative, set up this equation also
[tex]x - 9 = 10[/tex]
[tex]x = 1[/tex]
OR
[tex]x = 19[/tex]
Hal earns n dollars per hour. Next month he will receive a 2% raise in pay per hour. The expression
n + 0.02n is one way to represent Hal's pay per hour after the raise. Write an equivalent simplified
expression that will represent his pay per hour after the raise.
Answer:
1.02n
Step-by-step explanation:
A simplified version of this expression would be the following
1.02n
This is basically adding the n variables together. We do this by adding a 1 to the number being multiplied to n. This would basically add the 2% on top of what the original pay per hour is. We can prove that these two expressions are the same by substituting n for 10 in both expressions and solving them.
1.02n
1.02 * 10 = 10.2
n + 0.02n
10 + 0.02*10
10 + 0.2 = 10.2

Rajek, a truck driver, hauls containers for his customers. One customer wants to know the total amount of cardboard that can fit in a container at one time. The truck Rajek uses is shown below.
The base of the container has an area of 50 1/4 square feet.
Answer:
226 1/8
Step-by-step explanation:
Substitute the measurements of the container into the formula.
The amount of cardboard Rajek can fit in the container at one time is cubic feet.
The total surface area of the container is 9L + 9W + 50 1/4
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To find the total amount of cardboard that can fit in the container at one time, we need to find the surface area of the container.
The container has a rectangular base with an area of 50 1/4 square feet.
Let's assume the length of the base is L and the width is W.
We know that:
L x W = 50 1/4
We also know that the height of the container is 4(1/2) feet, which is equivalent to 9/2 feet.
The container has two identical sides, which are rectangles with a length of L and a height of 9/2 feet.
The surface area of one side is:
L x (9/2) = (9/2)L
The container also has two identical ends, which are rectangles with a width of W and a height of 9/2 feet.
The surface area of one end is:
W x (9/2) = (9/2)W
Finally, the container has a top, which is a rectangle with a length of L and a width of W.
The surface area of the top is:
L x W
To find the total surface area of the container, we add up the surface area of each of these parts:
Total surface area = 2(L x (9/2)) + 2(W x (9/2)) + (L x W)
Simplifying this expression, we get:
Total surface area = 9L + 9W + LW
We know that L x W = 50 1/4, so we can substitute this into the equation:
Thus,
The total surface area of the container is 9L + 9W + 50 1/4

What is the scale factor going from smaller to larger?
(reference photo please)
Step-by-step explanation:
Part A: Let see what number we can multiply by 3 to get 13.5
[tex]3x = 13.5[/tex]
[tex]x = 4.5[/tex]
so our answer is 4.5
Part B : Set up the proportion
3 and 13.5 correspond with each other and the question mark side corresponds with the 9 cm side.
let x = the side we are trying to find
[tex] \frac{3}{x} = \frac{13.5}{9} [/tex]
Cross multiply

Answer:
x = 8
Step-by-step explanation:
Apply the exterior angle theorem.
Thus:
45 + 6x + 7 = 13x - 4
Add like terms
52 + 6x = 13x - 4
52 + 6x - 13x = 13x - 4 - 13x
52 - 7x = -4
52 - 7x - 52 = -4 - 52
-7x = -56
-7x/-7 = -56/-7

Which resource is a renewable resource?
coal
O gemstones
metal
trees
Answer:
trees
Step-by-step explanation:
Trees are renewable resources. Trees can be planted, grown up, and harvested for timber. Forests are a different thing, however. A forest is a mature ecosystem.
Trees are renewable resource.
Option D is correct.
What is Renewable Resource?A renewable resource is one that can replace itself spontaneously over time. As a result, despite human usage, it is sustainable.
Renewable resources are particularly important because of their potential to replace non-renewable, or finite, resources in energy production. Furthermore, renewable resources can provide cleaner energy solutions than nonrenewable resources such as coal and fossil fuels.
Coal, gemstones, and metals are considered as non-renewable resources since they can be exhausted and are not available for lengthy periods of time. They are used as time goes on.
Thus, Trees are Renewable resources.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD = 4
and DC = 9, what is the length of BD? (Note: the figure is not drawn to scale.)
Answer:

Theorem: The altitude to the hypotenuse of a right triangle is the mean proportional between the segments of the hypotenuse.
So, [tex]\frac{4}{BD} = \frac{BD}{9}[/tex]
[tex]BD^{2} = 36[/tex]
BD = 6

60
Step-by-step explanation: will from the other two degrees added together then subtract from 180 and boom there's your answer
Answer:
x=8
Step-by-step explanation:
The sum of angles of any triangle=18076+44=120
so to get the value of the remained angle subtract that from 180
180-120=60
so
8x-4=60 add 4 to both sides
8x=64 divide both sides by 8
x=8
