Answer 2
Question: (3x-2)² + (2x-4)² = 3

Answer:

When squaring things, we are just multiplying it by itself (a² = a x a). When squaring brackets, it’s the same rule:

Therefore:

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

And using this skill we get:

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

Using FOIL:

9x²-6x-6x+4 + 4x²-8x-8x+16 = 3

Simplify:

13x²-28x+20 = 3

Take -20 off from both sides:

13x²-28x = -17

There’s your answer!

I hope this made sense, if you have any questions or you think I made a mistake somewhere please let me know!

Nisha has invited a group of friends over for a spaghetti dinner. There will be eight people dining, and Nisha would like to prepare 1 1/2 cups of cooked spaghetti per person. How many 16 oz. packages of dry spaghetti must Nisha use, and in how much water should she cook the pasta?

Remember, it takes 4 oz. of dry spaghetti to produce 2 cups of cooked spaghetti, and each 4 oz. of dry spaghetti requires 1 quart of water.

Answers

2 dry packages of spaghetti and 6 quarts of water. If 4 oz. equals 2 cups, then 3 oz. equals 1 1/2 cups of spaghetti. I multiplied the 3 oz. by the eight guests and got 24. Then, I took the 24 oz and divided that by 4 to get the quarts of water.

What is the circumference of Circle O?

Answers

Answer:

[tex]14\pi[/tex]

Step-by-step explanation:

The formula for finding the circumference of a circle is 2 times pi times the radius.

Looking at the picture, we can see that the radius of the circle is 7 cm. Plugging that into the formula gives:

2*[tex]\pi[/tex]*7 = 14[tex]\pi[/tex]

Answer: 14π cm or 43.98 cm.

Step-by-step explanation: To find circumference, one must use the equation c = 2πr (c = circumference and r = radius). Plugging in the values, we get 2πr = 2*π*7 which = 14π or if you want it rounded: 43.98 cm.

The relationship between a distance in yards and the same distance in miles is described by the equation y=1760m. Find measurements in yards and miles for distances by completing the table.
(Second question) is there a proportional relationship between a measurement in yards and a measurement in miles for in the same distance? Explain why or why not

Answers

Answer: Question 1:

Distance Measure in miles | Distance measured in yards

---------------------------------------------------------------------------------

                   1                        |                       1760

---------------------------------------------------------------------------------

                  5                        |                       8800

---------------------------------------------------------------------------------

                  2                        |                       3520

---------------------------------------------------------------------------------

                  10                       |                       17600

---------------------------------------------------------------------------------

Question 2:  

Yes, there is a proportional relationship between a measurement in yards and a measurement in miles, since a change in one variable leads to a direct change in the other variable, and there exists a constant ratio between them.

If y varies directly with x and y = 24 when x = 6, find x when y = 44.
