Answer

<em>length = width + 15</em>

<em>Area = length * width; area is 54 square feet.</em>

<em>Two equations are:</em>

<em>L = W + 15</em>

<em>L * W = 54</em>

<em>To solve, we substitute first equation into second equation:</em>

<em>(W + 15) * W = 54</em>

<em>w^2 + 15w = 54</em>

<em>w^2 + 15w - 54 = 0</em>

<em>(w+18)(w-3) = 0</em>

<em>w = -18 or 3</em>

<em>The width cannot be negative, so 3 is the width and since length is 15 more than width, length is 18:</em>

<em />

<em>Length = 18 feet</em>

<em>Width = 3 feet</em>

<em />

<em />

Solve the equation, 3x – 6 = 12, for x. Which of the following properties did you apply? Question 20 options: A) Distributive pr
Luda [366]

Answer:

C) Addition property of equality and division property of equality

Step-by-step explanation:

To find the answer, let's first solve the equation for x...

3x-6=12

Add 6 to both sides (Addition property of equality)

3x=6

Divide both sides by 3 (Division property of equality)

x=2

We used both the addition property of equality and the division property of equality therefore the answer is C

Solve this equation 4(2)-3= 2(2) + 9​
strojnjashka [21]

Answer:5=13

Step-by-step explanation:

Open parenthesis so you do 4 time 2 and 2 times 2. you get 8-3=4+9. 8-3=5 and 4+9=13. So your final answer is 5=14. I am not sure if you can simplify it further.

How many solutions does the equation 3x − 7 = 4 + 6 + 4x have? (5 points) Two None Infinitely many One
statuscvo [17]

Answer:

There is one solution.

x = -17

<em>Proof and step-by-step explanation:</em>

Step 1: <em>Add the numbers</em>

3x-7 = 4+6+4x

3x-7 = 10+4x

Step 2: <em>Move</em><em> </em><em>terms</em>

3x-7 = 10+4x

3x-4x = 10+7

Step 3: <em>Collect the like terms and calculate the sum</em>

3x-4x = 10+7

-x = 17

Step 4: <em>Change the sign by multiplying both sides by -1</em>

-x (×-1) = 17 (×-1)

x = -17

I hope this helped ! :)
