Answer:
-16c² + 1
Step-by-step explanation:
Use FOIL.
First: -4c × 4c = -16c²
Outside: -4c × 1 = -4c
Inside: 1 × 4c = 4c
Last: 1 × 1 = 1
-16c² - 4c + 4c + 1
Simplify.
-16c² + 1
Make sure you're starting with the highest degree term and going down; that's what standard form means. In this case -16c² has the highest exponent so it goes first, and then 1 doesn't have any variables, so it comes next.

Part of the roof of a factory is devoted to mechanical support and part to green space. The area G that is designated as green space can be modeled by the polynomial 2x^2 - 7x and the area M that is devoted to mechanical support can be modeled by the polynomial x^2 - 9x + 24. Given that the area R of the roof is 36 square yards, write and solve a quadratic equation to find the total area of the green space. **Use the positive value for your solution.

Volume of a Triangular Prism Formula
Is used To Find the 3-D space/ volume occupied by a triangular prism.
V=1/4h√((c+a−b)(a+b−c))× √((a+b+c)(b+c−a))
side length a = 4
side length b = 5
side length c = 3
prism height h = 8
V=1/4h√((c+a−b)(a+b−c))× √((a+b+c)(b+c−a))
V=1/4(8)√((3+4−5)(4+5−3))× √((4+5+c3)(5+3−4))
V= 48cm³

3.15 + 0.96 + 2(1.23) = 6.57
20-6.57 = 13.43
Tamara stacked two cubes, as shown. 2 stacked cubed. One cube has side lengths of 24 inches, and the second cube has side lengths of 12 inches. What is the total volume of the cubes? 1st cube volume: V = Bh V = (12)(12)(12) 2nd cube volume V = Bh V = (24)(24)(24) The total volume of the cubes is cubic inches.
Answer:
15 552 in³
Step-by-step explanation:
Since cubes have the same side lengths all around, to find the volume, you need to have one side length and cube it.
Cube 1 : 24³ = 24 x 24 x 24 = 13 824 in³
Cube 2 : 12³ = 12 x 12 x 12 = 1 728 in³
Now, to find the total, just add the volumes.
13 824 + 1 728 = 15 552 in³
The total volume of the cubes is V = 15,552 cubic inches
What is the Volume of a Cube?The formula of volume of the cube is given by:
Volume of Cube = a x a x a
Volume of Cube = a³
where a is the length of its sides or edges
Given data ,
The volume of the first cube with side length of 24 inches is given by:
V1 = (24 inches)³ = 13,824 cubic inches
The volume of the second cube with side length of 12 inches is given by:
V2 = (12 inches)³ = 1,728 cubic inches
The total volume of the two cubes is the sum of their volumes:
Total volume = V1 + V2 = 13,824 + 1,728 = 15,552 cubic inches
Hence , the total volume of the cubes is 15,552 cubic inches

Kelly bought 3 bracelets and 4 necklaces. She spent between $39 and $59. Each bracelet costs the same amount. Each necklace costs the same amount. The price of a bracelet is $5. How many dollars was the necklace?
Answer:
1 necklace will therefore cost 34/4 = $8.5
Step-by-step explanation:
She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.
At an average, she spent $49.
The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.
Thus $49 - $15 = amount spent on the 4 necklaces = $34.
4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5

Ellen "The Wonderer" continues to walk in the path of an inscribed polygon. She starts at W, walks south until the boundary point E, turns 70 degrees and walks east till S, turns 100 degrees, and walks north to point T. Determine how many degrees Ellen must turn to get back to her starting point.
Answer:
110°
Step-by-step explanation:
The path in the inscribed polygon walked by Ellen is shown in the diagram attached. Let the degrees in which Ellen must turn to get back to her starting point be T. Therefore to calculate T we use the theorem "An inscribed quadrilateral whose vertices all lie on a circle, the opposite angles of such a quadrilateral are in fact supplements for each other i.e their sum is 180 degrees."
Therefore: T + 70° = 180°
T = 180° - 70°
T = 110°
To get back to the starting point, Ellen must turn 110°

Huixian needs 171 pens , 63 pencils and 27 erasers into identical gift bags so that each item is equally distrusted among the gift bags . Find the number of each item in a gift bag
Answer:
57 pens per bag
21 pencils per bag
9 erasers per bag
Step-by-step explanation:
Here, we are to distribute a specific portion of each of the items in each of the gift bags.
What we must take into consideration is that the number of items per gift bag must be equal.
Thus, what we do is to divide the total number of each item by 3 to get exactly the number of each items that would be in each of the gift bags
For the pens, we have 171/3 = 57 pens per bag
For the pencils, we have 63/3 = 21 pencils per bag
For the erasers, we have 27/3 = 9 erasers per bag

Calculate the value of sin X to four decimal places
Answer:
0.7241
Step-by-step explanation:
sin = [tex]\frac{opposite}{hypotenuse}[/tex]
In this case we have the hypotenuse (2.9) but not the opposite so here is how you calculate it
[tex]a^{2}+b^{2}= c^{2} \\\\2^{2}+ b^{2}= 2.9^{2} \\4+ b^{2} = 8.41\\\\\sqrt{b^{2} }= \sqrt{4.41} \\b= 2.1[/tex]
So now you have the opposite (2.1)
so now you would divide [tex]\frac{2.1}{2.9} or 0.7241[/tex]
Answer:
[tex] \sin X = 0.7241 [/tex]
Step-by-step explanation:
For angle X, 2.0 ft is the adjacent leg. 2.9 ft is the hypotenuse.
The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.
[tex] \cos X = \dfrac{adj}{opp} [/tex]
[tex] \cos X = \dfrac{2.0}{2.9} [/tex]
[tex] \cos X = 0.689655 [/tex]
Since we now know the value of cos X, we can find the value of sin X by using the trig identity
[tex] \sin^2 X + \cos^2 X = 1 [/tex]
[tex] \sin^2 X + (0.689655)^2 = 1 [/tex]
[tex] \sin^2 X = 0.524376 [/tex]
[tex] \sin X = 0.7241 [/tex]

Answer:
y-1 = -(x-2)
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= (5-1)/(-2 -2)
= 4/-4
= -1
We are using point slope form using the point (2,1)
y-y1 = m(x-x-1)
y-1 = -1(x-2)
y-1 = -(x-2)
