Answer: x = 17

Step-by-step explanation: Factor the equation to get

(x - 5)² = 144

Take the square root of each side to get

x - 5 = 12 Add 5 to both sides.

x = 17

Check:

17² - 10(17) + 25 = 144

289 - 170 + 25 = 144

119 +25 = 144. true.

92.96 as a fraction
nikklg [1K]
To change a decimal to a fraction you need to first place the decimal over 1. Next, for each number behind the decimal, you will multiply by a multiple of 10. Since there are 2 numbers behind the decimal, it's 100. Therefore, 
92.96 x 100 = 9296
1 x 100= 100


Your new fraction is 9296/100. Now we simplify it. I'm going by 2's so it may take a bit. 
Simplifying it twice by 2's your answer would be:

2324/25

Which is the area of a square with one side that measures 1 foot? A. 1 square inch B. 100 square inches C. 144 square inches D.
cluponka [151]

Answer:

Option C. 144 square inches is the correct answer.

Step-by-step explanation:

We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.

First we know that 1 foot of length = 12 inches on scale

Therefore side of the square is 12 inches

Now the area of the square will be = (Side×Side) = (Side)²

                                                          = (12)² = 144 square inches.

So the area of the square will be 144 square inches.
