Perimeter is the boundary of a closed geometric figure.It may also be defined as the outer edge of an area, simply the longest continuous line that surrounds a shape. The name itself comes from Greek perimetros: peri meaning "around" + metron, understood as "measure".As it's the length of the shape's outline, it's expressed in distance units - e.g., meters, feet, inches, or miles.

Step-by-step explanation: 1. Let's simplify the following expression: x squared plus 3 x plus 2 over x plus 1. (x ² + 3x + 2) / (x + 1) Now, we are going to factorize the numerator, this way: (x + 2) (x + 1) / ( (x + 1) x * x = x ²; 2x + x = 3x ; 2 * 1 = 2 ⇒ x² + 3x + 2. We simplify (x + 1) both in the numerator and in the denominator and
Evaluate 14 plus 16 square root 3. The given expression is 14 + 16 √3. We know that the square root of 3 is 1.732. Therefore, 14 + 16 √3 = 14 + 16 × 1.732 = 14 + 27.713 = 41.713. Is the number 3 a Perfect Square? The number 3 is prime. This implies that the square root of 3 cannot be expressed as a product of two equal integers.
Here are some less common mathematical terms: el cuadrado de — the square of. el cubo de — the cube of. ecuación — equation. elevado a la enésima potencia — raised to the nth power. función — function. número imaginario — imaginary number. promedio — average, mean. quebrado, fracción — fraction. They're 1, 3, and 9. So this could be a 3 and a 3, or it could be a 1 and a 9. Now, if it's a 3 and a 3, then you'll have 3 plus 3-- that doesn't equal 10. But if it's a 1 and a 9, 1 times 9 is 9. 1 plus 9 is 10. So it does work. So a could be equal to 1, and b could be equal to 9. So we could factor this as being x plus 1, times x plus 9. 3(x-1) Since the expression is a DIFFERENCE, subtraction will be involved. As an example, the difference of 7 and 5 would be written as 7-5. Therefore, the difference of a number and one can be represented by the expression x-1, where x can be equal to any number. If we want to find 3 times that difference, we multiply 3 by what we already have: 3(x-1) Note that this is also equal to 3x-3 if .
