4 × ( x + 4 ) = 3 × ( 3 + 5 )

4 × ( x + 4 ) = 3 × 8

Divide both sides by 4

x + 4 = 3 × 2

x + 4 = 6

Subtract both sides 4

x = 2

Which expression is equivalent to x³ - x² - 14x + 24?
serg [7]

Answer:

<h3>A. ( x - 2 )( x - 3 )(x + 4 )</h3>

<h3>Step-by-step explanation:</h3>

<h3>x³ - x² - 14x + 24</h3>

<h3>1. Use the rational root theorem</h3>

= (x  - 2) \frac{x ^{3}  -x^{2}  - 14x + 24}{x - 2}

<h3>2. \frac{  {x}^{3} - {x}^{2}  - 14x + 24 }{x - 2}  =  {x}^{2}  + x - 12</h3><h3 />

= ( x - 2 )( x² + x - 12 )

<h3>3. Factor x² + x - 12 : ( x -3 )( x + 4)</h3>

= ( x - 2 )( x - 3 )(x + 4 )

<h3>Solution : </h3>

<h3>= ( x - 2 )( x - 3 )(x + 4 )</h3>

Please help me answer Questions A &amp; B. I have Plenty of Points
inna [77]

1) To get equation B from equation A, we will add a quantity to the left hand side of equation A. The correct option is A. Add/subtract a quantity to/from only one side

2) The equations are not equivalent. They do not have the same solution

<h3>Equations</h3>

From the question, we are to determine how we can get equation B from equation A

From the given information,

A. 5x - 2 + x = x - 4

B. 5x + x = x - 4

From above, we can observe that to get equation B from equation A, we will add 2 to the left hand side of equation A

That is

5x - 2 + 2 + x = x + 4     →     5x + x = x + 4

Hence, to get equation B from equation A, we will add a quantity to the left hand side of equation A. The correct option is A. Add/subtract a quantity to/from only one side

2) The equations are not equivalent. They do not have the same solution

Shawna and her best friend Keisha go shopping. The function p(t) = 3x +2x-4x2+ 21 represents how much money each girl spent base
NNADVOKAT [17]

Answer:

\$30

Step-by-step explanation:

we have

p(t)=3x+2x-4x^{2}+21

<em>Find the amount of money that each girl spent</em>

For t= 2 hours

p(2)=3(2)+2(2)-4(2)^{2}+21

p(2)=10-16+21

p(2)=\$15

<em>Find the amount of money that they spend together</em>

Multiply by 2 the amount of money that each girl spent

(2)\$15=\$30
