Answer:
try desmos, type in the equation and it shows you the graph
Step-by-step explanation:
Method One:
Step One: Figure out how long the width is, witch is 19 feet.
Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide
Step Three: Add 38+33
The new perimeter will be 71 feet.
Answer:
You should add 4 to both sides because that would make the left side a perfect square which is what you are intending to do when you complete the square.
Answer:
30
Step-by-step explanation:
RT is a transversal, and since the sides of the parallelogram are parallel, angle QTR is equal to angle SRT, so angle SRT is 30 degrees. Since the side opposite the 30 degree angle in a right triangle is equal to half the value of the hypotenuse, RS is double TS, making RS equal to 10. Since opposite sides of a parallelogram are congruent, QR = 5 and QT = 10. We add up all the values of the sides to get a perimeter of 30.
