Answer:

A = 3x^2 - 2x - 1

Step-by-step explanation:

3x times x equals 3x^2

(3x times - 1) + (x times 1) = -2x

1 times -1 = -1

put the partial products together, you get the above answer.

Someone help me with this !!!

charle [14.2K]

Answer:

150°

Step-by-step explanation:

to find the individual angle of a REGULAR dodecagon (which means that all sides are equal), you'd use the equation I(individual angle)= (n-2)×180/n

N is number of sides. The number of sides on a dodecagon is 12. So, substitute N for 12

I= (12-2)×180/12 which simplifies to 10×180/12

10×180= 1800

1800/12 = 150

so, an individual interior angle of a dodecagon is 150°

what is the measure of the vertex angle of an isosceles triangle i’d one of its base angles measures 42°

Naya [18.7K]

The measure of the vertex angle of the isosceles Δ is 96°

Step-by-step explanation:

In the isosceles triangle

Two sides are equal in lengths
The angle between the two equal sides is called vertex angle
The other two angles are called base angles
The base angles are equal in measure

∵ The measure of one of the base angles of an isosceles Δ = 42°

- The base angles are equal in measure

∴ The measure of the other base angle = 42°

∵ The sum of the measures of the interior angles of any Δ = 180°

∴ 42 + 42 + measure of the vertex angle = 180

∴ 84 + measure of the vertex angle = 180

- Subtract 84 from both sides

∴ measure of the vertex angle = 96°

The measure of the vertex angle of the isosceles Δ is 96°

The array has 32 squares.what are the side

Vinil7 [7]

Solution:

Array is arrangement of numbers in terms of rows and columns either by rectangles or squares.

So,if an array has 32 squares

The possible arrangements are

32 = 8× 4 or 4× 8

= 16×2 or 2×16

= 1 ×32 or 32 ×1

Here first entry denotes number of rows and second entry denotes number of columns.

Factor the polynomial completely using the X method. X2 13x – 48 An x-method chart shows the product a c at the top of x and b a

Ratling [72]

X method is the method to find the factors of the polynomial equation.The factor of the given polynomial is,

$x^2+16x-3x-48=(x+16)(x-3)$

Thus the option 3 is the correct option,

<h3>How to find factor of polynomial using X method?</h3>

X method is the method to find the factors of the polynomial equation.

The standard form of the quadratic equitation is given as,

$ax^2+bx+c$

Given information-

The equation given in the problem is,

$x^2+13x-48$

Compare the above equation with the standard form. We get,

$a=1\\b=13\\c=-48$

To find out the factor of above equation using X method, follow the steps.

Step 1) Multiply $a$ and $c$ and place $ac$ at the top of X as shown in the image.

$ac=1\times(-48)\\ac=-48$

Step 2) Place $b$ at the bottom as shown in the image below.

$b=13$

Step 3) Find two numbers that multiply the top number $ac$ and to the bottom number $b$ .

Step 4) Write the polynomial from the X box as,

$x^2+16x-3x-48=x(x+16)-3(x+16)$

$x^2+16x-3x-48=(x+16)(x-3)$

Hence the factor of the given polynomial is,

$x^2+16x-3x-48=(x+16)(x-3)$

Thus the option 3 is the correct option,
