Help is it A or B? pls help

Damm [24]

Answer:

$f(x)=-(x+8)(x-2)$

Step-by-step explanation:

Start by factoring out a -1...

$f(x)=-(x^2+6x-16)$

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

$f(x)=-(x^2-2x+8x+16)$

Factor the first and second half separately...

$f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\$

Since both x and 8 are being multiplied by x-2, we can combine them to get...

$f(x)=-(x+8)(x-2)$

A Cone has a radius of 3 and a height of 5. solve.

Alexus [3.1K]

Assuming your looking for volume.

The following formula is used for calculating the volume (V) of a cone.

$\boxed{V=\frac{1}{3}\pi r^{2} h}$

where r is the radius and h, the height.
Substitute r = 3 and h = 5 into the formula.

⇒ $V=\frac{\pi *3^{2} *&5}{3} =\frac{45*\pi }{3}$ ≈ $47.124$ $cubic$ $cm$

The sum of three co secutive numbers is 72 what are the smallest of these numbers

dybincka [34]

Step-by-step explanation:

The question above is answered below.

Consecutive numbers are set of numbers that follow one another in ascending or descending order, e.g. 1, 2, 3, 4, 5....

The sum of three consecutive numbers = 72

Let the unknown consecutive numbers be represented by x+1, x+2 and x+3 such that:

$(x + 1) + (x + 2) + (x + 3) = 72$

Remove the brackets

$x + 1 + x + 2 + x + 3 = 72$

Collect like terms and simplify

$x + x + x + 1 + 2 + 3 = 72$

$3x + 6 = 72$

Make 3x subject of formula by subtracting 6 from both sides

$3x + 6 - 6 = 72 - 6$

$3x = 66$

To obtain the value of x, divide through by the coefficient of x, which is 3. Hence;

$\frac{3x}{3} = \frac{66}{3}$

$x = 22$

Since x = 22,

$x + 1 = 22 + 1 = 23$

$x + 2 = 22 + 2 = 24$

$x + 3 = 22 + 3 = 25$

The smallest of these numbers is 23.

Check,

23 + 24 + 25 = 72

A bulk store sells 200 diapers from Brand (a) for $38.75 and it says 170 diapers from Brand (b) for $35.50. If both brands have

Mazyrski [523]

Answer:

Brand A costs less per diaper

Step-by-step explanation:

To determine if it is the better deal, we need the cost per diaper. To find the Cost per diaper, take the total cost and divide by the number of diapers

Brand A

Cost per diaper = $38.75/ 200 = $.19375 per diaper

Brand B

Cost per diaper = $35.50/170 =.208823529 per diaper

Brand A costs less per diaper
