Answer:

-12x^2+6x

Step-by-step explanation:

-3x(4x-2)

-12x^2+6x

The standard form of the polynomial is -12x² +6x.

A polynomial is an equation made up of exponents, constants, and variables that is combined using mathematical operations including addition, subtraction, multiplication, and division.

The given expression is  – 3x (4x - 2)​

Solving further,

–3x (4x - 2)​

=-12x² +6x.

The standard form of the polynomial is -12x² +6x after multiplying  – 3x (4x - 2)​

Answer:

16 to 9

Step-by-step explanation:

Represent donut with frosting with D1 and donut without frosting with D2.

So, we have:

[tex]D_1 = 32[/tex]

[tex]D_2 = 18[/tex]

Required

Find the ratio of D1 to D2

This is calculated as:

[tex]D_1 : D_2[/tex]

Substitute values for D1 and D2

[tex]D_1 : D_2 = 32 : 18[/tex]

Divide by 2

[tex]D_1 : D_2 = 32/2 : 18/2[/tex]

[tex]D_1 : D_2 = 16 : 9[/tex]

The ratio of donuts with frosting to donuts without is 16 to 9

Answer:

b) 256 inches

Step-by-step explanation:

8x5x2 = 80   (top & bottom)

8x5x2 = 80    (front & back)

8x8x2 = 128    (gross area of 2 sides)

4x4x2 =32      (delete this for side cutouts) Guessing the cutoff dimension on

                                                                       left side is 4m inch.

80+80+128-32 = 256 inches

Answer:

No. pp you can fit in a van: 6,

No. pp you can fit in a bus: 20

Step-by-step explanation:

Let v = # of pp in vans, and let b = # of pp in buses:

8v + 9b = 228,

4v + 5b = 124

If we solve this system of equations by substitution, we isolate the first eq. for v and then substitute into the bottom eq:

v = 228-9b/8,

Substitute v = 228-9b/8 into bottom eq:

[4 * 228-9b/8 + 5b = 125]

[228+b/2=124]

[228+b = 248]

[b = 20]

Now substitute 20 to find no. of pp in the vans:

v = 228 - 9(20)/8 = 228  - 180/8 = 48/8 = 6

Answer:

[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]

Step-by-step explanation:

This function can be written as:

[tex]\frac{1}{cos(sin^{-1}(\frac{1}{2x})) }[/tex]

[tex]sin^{-1}(\frac{1}{2x})[/tex] means the angle whose sine is 1/(2x).  This implies that the denominator is the cosine of the angle whose sine is 1/(2x)

Think of a right triangle and consider the angle with this sine.  Then the opposite side has length 1 and the hypotenuse has length  2x.  The Pythagorean theorem then implies that the adjacent side is

[tex]\sqrt{4x^{2} -1}[/tex]

The cosine of the angle is adjacent over hypotenuse, so the cosine is

[tex]\frac{\sqrt{4x^{2} -1}}{2x}[/tex]

The secant is the inverse of the cosine, so the answer is

[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]

Answer:

Maggie is incorrect.

Step-by-step explanation:

PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 before dividing.

I hope this helps!

Answer:

£3692

Step-by-step explanation:

A = p(1 + r/n)^nt

Where,

A = future value

P = principal = £2350

r = interest rate = 4.2% = 0.042

n = number of periods = 1(annual)

t = time = 4 years

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Total years = 10

Remaining years = 10 - 4

= 6 years

Remaining 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692

-3

Answer:

Yes

Step-by-step explanation:

We have two properties for our question :

(4, 27)

y = 3x + 15

We are being asked whether the point (4, 27) is a solution of y = 3x + 15

So how do we figure this out? Well, what we have to know first that (4, 27)  represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.

y = 3x + 15

y = 27 and x = 4

27 = 3(4) + 15

27 = 12 + 15

27 = 27

Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

Answer:

3.03*[tex]10^{-4}[/tex]

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We're given the adjecent and we're looking for the hypotenuse so we'll have to use cosine ratio.

11 / cos 38 = 13.959.....

x = 14.0

We can also use the tangent ratio to look for the opposite and then use pythagorean to find the hypotenuse.

11(tan 38) = 8.594......

8.594.....² + 11² = 194.859......

Square root of 194.859..... = 13.959.......

Answer:

% = 50

Step-by-step explanation:
