x+x^2 = 12
x^2+x-12=0
(x+4)(x-3)=0
X = -4 or 3
Answer is 3.
CHECK YOUR ANSWER:
3 + 3^2 = 3+9 = 12
1 inch by 24 inches equals 24 square inches 10 inches by 2.4 inches equals 24 square inches 100 inches by 0.24 inches equals 24 square inches 1000 inches by 0.024 inches equals 24 square inches also: 2 inches by 12 inches equals 24 square inches 2.5 inches by 9.6 inches equals 24 square inches 3 inches by 8 inches equals 24 square inches 3.2 inches by 7.5 inches equals 24 square inches 4 inches by 6 inches equals 24 square inches This list could be very long.
-3
Depends on how big they are. The resulting number could be positive or negative. Negative 1/4 and Positive 1/2 will be a Positive 1/4. Positive 1/4 and Negative 1/2 will be a Negative 1/4.
Yes, every positive real number has a real square root. If you would write your number in scientific notation, I could tell you what the root is.
To find the area you multiply 138 X 80 this equals 11,040 square ?? You don't say what units you are using so the answer could be square metres, square feet, square yards etc
9 = sr, could mean "9 equals square root of 81".

You are asking for the square root of 117649 - which is 343 (which you could get by using the square root function on most calculators).
-3
That would be its square root, or 11.286..; it could be positive or negative
It could be any size where the length times the width equals 3,444.

The answer is an imaginary number, because of the negative under the square root. The same number multiplied together will always be a positive number. For example, if you square negative one, the answer is positive one, because a negative times a negative is a positive. Because a square root undoes a square, there is no solution to the square root of a negative number. That's why your calculator could not compute this problem. However, there is a way to solve these types of problems by using imaginary numbers. The answer is 13i, where i is the square root of negative one.

Don't forget that a positive number squared is also positive.The rule has nothing to do with whether they're positive or negative. The rule is:When you multiply two numbers together, if their signs are the same then the product is positive.If their signs are different, then the product is negative.When you square a number, the two numbers you're multiplying are the same number,so their signs are always the same, and the product (the square) is always positive.Going the other way, you start with a positive number that's the product. Since it's positive,you know that the two numbers that were multiplied to get it have the same sign ... theycould both be positive, or they could both be negative.The answer to your question is more weird than you expected: The square root of a positive numberis negative. It's also positive. A positive number has two square roots ... the positive one andnegative one.Now, the square root of a negative number is something more difficult. No number squared can equal a negative except for what is called imaginary numbers, defined by "i". For example, the square root of -1 is i, and the square root of -2 is (√2)*i.
It could be either positive or negative, depending on which integer has a greater absolute value. 5 + (-3) = 2 5 + (-9) = -4
