Is p(4p - 9) =12 or p(4p - 9) - 12 quadratic?

pls need help
From: Brainly.ph (philippines​)

Answers

Answer:

p(4p - 9) =12 ⇒ 4p² - 9p = 12 ⇒ 4p² - 9p - 12 = 0

This is a quadratic equation

p(4p - 9) - 12 ⇒ 4p² - 9p - 12

This is a quadratic expression

Step-by-step explanation:

p(4p-9)=124p²-9p=12

Since, it's one term has power 2 ,so it is quadratic

p(4p-9)-124p²-9p-12

Since, it's one term has power 2, so it is quadratic

Answers

Answer: Part A: a square pyramid Part B: 84 square feet

Step-by-step explanation:

Part A: The shape will have a base that is a square with triangles on each of its edges that connect at a point at the top.

Part B: The amount of nylon needed is the surface area of the net. There is a square and two triangles. The square has a side length of 6 so its area will be 6*6=36 square feet. Each triangle has a base of 6 and a height of 4 so each of their areas will be [tex]\frac{6*4}{2}=12[/tex] square feet. Adding up the area of the 4 triangles and the square gives us 4*12+36=84 square feet.

Answer:

9

Step-by-step explanation:

Answer:

The GCF is going to be 9

Step-by-step explanation:

When finding the GCF, you want to do prime factorization of each number.

18's prime factorization is, 2 × 3 × 3, which equals 18

36's prime factorization is 2 × 2 × 3 × 3, which equals 36

45's prime factorization is 5 × 3 × 3, which equals 45

Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer

Hanks pickup can travel 45 miles on 3 gallons of gas. How many gallons will Hanks pickup need to travel 30 miles?

Answers

2 gallons because 45/3=15 30/15=2

We have an algebra problem.

We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.

The information given is:

The pickup can travel 45 miles on 3 gallons of gas.

To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)

This is:

r = (45 miles)/(3 gallons) = 15 miles/gallon.

Now that we know this, the number of gallons needed to travel 30 miles is given by:

N = (30 miles)/(15 miles/gallon) = 2 gallons.

N = 2 gallons.

The pickup needs 2 gallons to travel 30 miles.

What is the common difference of the following sequence? 27, 11, -5, -21, -37, . . .

Answers

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.

Step-by-step explanation:

mark me brainliest plz

Answer:
