Answer:

Hello!

After reading the question you have provided I have come up with the correct numerical expression:

4x5-1

Step-by-step explanation:

To come up with this solution you need to keep in mind some of the terminoloy being used.

The word "subtract" comes from the action of subtraction

The word "product" comes from the action of multiplication

Thus, using those terminologies correctly, you can then deduce that when the question says "the product of 4 and 5" means "multiplying 4 and 5 together".

So you get the first part being 4x5

Then, you add in the last part of "subract 1" from the "product of 4 and 5":

4x5-1

<em>Remember to keep in mind the rule of "PEMDAS"</em>

You always need to keep the multiplication portion of the equation in front of any subtraction, or addition in any given equation.

It would be (4 x 5) - 1

Though the parentheses aren’t needed here so

4 x 5 - 1

5x−2.5+6x−3= ___ (2x−1)
LiRa [457]

Answer:

5.5

Step-by-step explanation:

So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.

So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.

Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5

Now we have 11-5.5=?

so, we need to have (2x-1) in our answer because the problem asks for that in the answer.

We need to find a number that satisfies the equation and answer

so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.

5.5 satisfies the equation, therefore is the answer

A dog trainer is installing a small rectangular pen using at most 40 feet of fencing for three sides. The fourth side of the pen
likoan [24]

The 40 feet of fencing which covers at least 182 square feet gives the possible lengths of x as x ≥ 13 or x ≤ 7

<h3>How can the area be expressed as an inequality?</h3>

Length of the fencing = 40 feet

Number of sides covered = Three sides

Area of the fencing ≥ 182 square feet

Length of the shorter side of the pen = x

The area is therefore;

  • x × (40 - 2•x) ≥ 182

2•x² - 40•x + 182 ≥ 0

2•(x² - 20•x + 91) ≥ 0

2•(x² - 13•x - 7•x + 91) ≥ 0

2•(x•(x - 13) - 7•(x - 13) ≥ 0

  • 2•(x - 13)•(x - 7) ≥ 0

Which gives;

  • x ≥ 13 or x ≤ 7

The solution to the inequality and the possible lengths of <em>x </em>are;<em> </em>x ≥ 13 or x ≤ 7
