What is the perimeter of a square if it has an area of 49 square centimeters?
The perimeter would be 28 centimeters. This can be seen because all 4 sides are equal in a square, and the area is equal to two adjacent sides multiplied, so all you have to do is find the square root of 49 which is 7, so this is the length of each side, and the total preimeter is 4 times this which is 28.
Can a triangle with side lengths of 20 21 28 be a right triangle?
We could be able to tell this through the use of the Pythagorean theorem. Unfortunately, we may only be able to attempt this, If we assume that your hypotenuse is the last measurement. A and B can be either leg of the triangle, however, "C" must always be the hypotenuse.So we'll test out using each value as the hypotenuse.Pythagorean theorem: A2 + B2 = C2So using this we'll begin by a = 20, b = 21, c = 28:202 + 212 = 282400 + 441 = 784841 = 784841 does not equal 784Therefore, using 28 as the hypotenuse yields a triangle that is not a right triangle.Secondly, we'll use a = 20, b = 28, c = 21202 + 282 = 212400 + 784 = 4411184 = 4411184 does not equal 441Therefore, using 21 as the hypotenuse yields a triangle that is not a right triangle.Lastly, we'll use a = 28, b = 21, c = 20282 + 212 = 202784 + 441 = 4001225 = 4001225 does not equal 400Therefore, the measurements 20, 21, and 28, no matter which is used as the hypotenuse can yield a right triangle.

What mistake was made in this equation 3x plus 7 equals -4x plus 28 -x plus 7 equals 28 -x equals 21 x equals -21?
3x + 7 = -4x + 28 implies 7x + 7 = 28
What is the answer of 4a-7 equals 21?
21 + 7 = 28 28 / 4 = 7 Your answer is 7.
