Answer:

The answer is x^3 - 2x^2 - 24x

Step-by-step explanation:

(x+4)(x^2-6x)

= (x+4)(x^2 + -6x)

= (x)(x^2) + (x)(-6x) + (4)(x^2) + (4)(-6x)

=x^3 - 6x^2 + 4x^2 - 24x

=x^3 - 2x^2 - 24x

PLEASE HELP!! WILL GIVE BRAINLIEST!!!

Murrr4er [49]

Answer:

option D

Step-by-step explanation:

Jerry solved this equation:

$3(x-\frac{1}{4})=\frac{13}{6}$

In the first step , she multiplied 3 inside the parenthesis

1. $3x-\frac{3}{4}=\frac{13}{6}$

In step 2, 3/4 is added on both sides

2. $3x-\frac{3}{4}+\frac{3}{4}=\frac{13}{6}+\frac{3}{4}$

In step 3, we take LCD 12

3. $3x=\frac{26}{12}+\frac{9}{12}$

In step 4, add the fractions

4. $3x=\frac{35}{12}$

Here, 3 or 3/1 are same.

$\frac{3}{1}x=\frac{35}{12}$

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

$\frac{1}{3} \cdot \frac{3}{1}x=\frac{1}{3} \cdot \frac{35}{12}$

$x=\frac{35}{36}$

In step 5, he should have multiplied both sides by 1/3

12-2(n-1)=-18<br><br> aa help plzz

Luda [366]

Answer:

n=16

Step-by-step explanation:

Let's solve your equation step-by-step.

12−2(n−1)=−18

Step 1: Simplify both sides of the equation.

12−2(n−1)=−18

12+(−2)(n)+(−2)(−1)=−18(Distribute)

12+−2n+2=−18

(−2n)+(12+2)=−18(Combine Like Terms)

−2n+14=−18

Step 2: Subtract 14 from both sides.

−2n+14−14=−18−14

−2n=−32

Step 3: Divide both sides by -2.

−2n /−2 = −32 /−2

n=16

A rectangular sign has length of 3 and 1/2 ft and a width of 1 and 1/8 ft. Will the area of the sign be greater or less than 3 a

zavuch27 [327]

Answer:

$Area = 3\dfrac{15}{16}\ sq\ ft$

Area is greater than $3\frac{1}{2}$ sq ft.

Step-by-step explanation:

Length of rectangular sign board = $3\frac{1}{2}$ ft

Width of rectangular sign board = $1\frac{1}{8}$ ft

Area of a rectangle is given by the formula:

$A = Length \times Width$

To find the area, we are going to multiply $3\frac{1}{2}$ with $1\frac{1}{8}$ .

$1\frac{1}{8}$ is greater than 1.

Therefore the multiplication will be greater than $3\frac{1}{2}$ .

Hence, we can say that area will be greater than $3\frac{1}{2}$ sq ft.

Area of the sign:

$A = 3\dfrac{1}{2}\times 1\dfrac{1}8\\\Rightarrow A = \dfrac{7}{2}\times \frac{9}8\\\Rightarrow A = \dfrac{63}{16}\\\Rightarrow A = 3\dfrac{15}{16}\ sq\ ft$
