<em>Comment on answer choices</em>
Because the square of a number is the same as the square of its opposite, the formula in choice D is also correct.
Answer:
b. 40

Answer:
13 students
Step-by-step explanation:
4 plus 9 = 13
Answer:
so the first one unselect
the second one check it
the third one unselect
the fourth one check it
the fifth one check it
A= 20x25 so the area is 500
To find the perimeter you have to add both the width and length x2 so it’s 20+25 =45
45x2=90
