If she reflects across the x-axis, then the y-values will change.
The y-values will be opposite their original values.
(-6, -4) and (-2, -4) are the two new points after the transformation.
Hope this helps!
The perimeter of an object is given by the sum of all the sides of the object. Thus the perimeter of a quadrilateral is the sum of the four sides of the quadrilateral.
Given a quadrilateral with sides: n, 2n - 12, 3n + 4, n + 7
The sum is n + 2n - 12 + 3n + 4 + n + 7 = 7n - 1 = 90
Thus, 7n = 90 + 1 = 91 and n = 91 / 7 = 13.
Therefore, the length of the side KL is n = 13 centimeters.
When you combine like terms, you are able to solve the equation in less steps
P.E.M.D.A.S.
Parentheses, exponent, multiplication, division, addition, subtraction
1. First simplify the exponents in the set of parentheses
2. Next multiply the decimals to the simplified exponent
3. Last subtract both numbers
And there is your answer
40%= 0.40 if you think of the decimal being at the end of the number (40.%) than just move the decimal twice makes it 0.40
