Determine the solution for the polynomial:
14x^2 + 60x = -2(5x^2 + 3x - 9)
Determine if true:
3x12+12=48
Answer:
True
Step-by-step explanation:
3x12=36
3x12=3636+12=48
3x12=3636+12=4848=48
Hecne, the equation is true.
Answer: The left side 48 is equal to the right side 48. So this means that 3 × 12 + 12=48 is TRUE!

i will give brainiest
Answer:
I'm pretty sure this is the answer its 24 or 30
Step-by-step explanation:
Because first what you would do is round 2.4 to 2 then multiply it by 12 to get 24 if its not 24 it would be 28.8 then you round 28.8 to 30. Hope that helped! :)

=============================================
Explanation:
Recall that the pythagorean trig identity is [tex]\sin^2 x + \cos^2x = 1[/tex]
If we were to isolate sine, then,
[tex]\sin^2 x + \cos^2x = 1\\\\\sin^2 x = 1-\cos^2x\\\\\sin x = \sqrt{1-\cos^2x}\\\\[/tex]
We don't have to worry about the plus minus because sine is positive when 0 < x < pi/2.
Through similar calculations, [tex]\cos x = \sqrt{1-\sin^2x}\\\\[/tex]
Cosine is also positive in this quadrant.
-------------
So,
[tex]\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}\\\\\frac{\sin x}{\sin x}+\frac{\cos x}{\cos x}\\\\1+1\\\\2[/tex]
Therefore,
[tex]\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}=2[/tex]
is an identity as long as 0 < x < pi/2
Answer:
2
Step-by-step explanation:
[tex]=\frac{\sqrt{1-cos^{2}x }}{sinx} +\frac{\sqrt{1-sin^{2}x } }{cosx} \\\\When \:0 < x < \frac{\pi }{2} \\\\=\frac{\sqrt{sin^{2}x } }{sinx} +\frac{\sqrt{cos^{2}x } }{cosx} \\\\=\frac{sinx}{sinx} +\frac{cosx}{cosx} \\\\=1+1\\\\=2[/tex]
Here we use the formula sin²x=1-cos²x and cos²x=1-sin²x.
A guitar effects pedal enthusiast is going to a gear convention where people sometimes break out their own custom pedals to show off or trade. She has 5 different pedals she's thinking about packing with her, but she's not sure whether she should bring all of them, some of them, or none of them. How many different ways are there for her to decide whether and how many pedals to pack? Use subsets to help you figure this out, and write your answer as a whole number.
There are 32 different combinations that she can select out of the 5 pedals.
How many different combinations there are?
We want to get the total number of different combinations that we can make with 5 different pedals.
Remember that for a set of N elements, the number of different sets of K elements that we can make is:
[tex]C(N, K)=\frac{N!}{(N - K)!*K!}[/tex]
In this case, the total number of different combinations that we can make with the 5 pedals is given by:
C = C(5, 0) + C(5, 1) + C(5, 2) + C(5, 3) + C(5, 4) + C(5, 5).
Let's calculate each one of these:
[tex]C(5, 0) = \frac{5!}{(5 - 0)!*0!} = \frac{5!}{5!} = 1\\\\C(5, 1) = \frac{5!}{(5 - 1)!*1!} = \frac{5!}{4!} = 5\\\\C(5, 2) = \frac{5!}{(5 - 2)!*2!} = \frac{5!}{3!*2!} = \frac{5*4}{2} = 10\\\\C(5, 3)= \frac{5!}{(5 - 3)!*3!} = \frac{5!}{3!*2!} = \frac{5*4}{2} = 10\\\\\\C(5, 4) = \frac{5!}{(5 - 4)!*4!} = \frac{5!}{4!} = 5\\\\C(5, 5) = \frac{5!}{(5 - 5)!*5!} = 1[/tex]
So the total number of different combinations is:
C = 1 + 5 + 10 + 10 + 5 + 1 = 32

En la misma papelería, a Julián le cobraron $40 por 4 lápices y 8 plumas, mientras que a Estefanía le cobraron $25 por 6 lápices y 2 plumas. ¿Cuántos pesos costó cada pluma?
The cost of a pen is $3.5 while the cost of a pencil is $7
Simultaneous equationLet the price of pen be x
Let the price of pencil be y
If Julian was charged $40 for 4 pencils and 8 pens, then;
4y + 8x = 40
y + 2x = 10
y = 10 - 2x .............. 1
Similarly, if Estefania was charged $25 for 6 pencils and 2 pens, then;
6y + 2x = 25
Substitute 1 into 2 to have:
6(10-2x)+ 2x = 25
60 - 12x + 2x = 25
60-10x = 25
10x = 35
x = 3.5
Since y = 10 - 2x
y = 10 - 7
y = 3
Hence the cost of a pen is $3.5 while the cost of a pencil is $7

The fire in Atlanta
The surface area of one ornament is about ?inches squared
Answer:
183.9 square inches74 bottles of paintStep-by-step explanation:
The surface area of one ornament is twice the area of a cone with radius 2.4 inches and slant height 9.8 inches. The number of bottles of paint required will be found by dividing the total area to be painted by the area covered by one bottle.
__
The area formula for a cone is ...
A = πr(r +s) . . . . . radius r, slant height s
The area of the double cone ornament will be ...
A = 2(3.14)(2.4 in)(2.4 +9.8 in) = 183.8784 in²
The surface area of one ornament is about 183.9 square inches.
__
The surface area of 60 ornaments is ...
60 × 183.8784 in² = 11,032.704 in²
The number of bottles of paint required is ...
11,032.704 in²/(150 in²/bottle) = 73.55136 bottles
Tim will need 74 bottles of paint for 60 ornaments.
