Answer 1

Answer:

1) A quadrilateral is a closed figure with 4 sides. And as square, rectangle and parallelogram have four sides, they are called quadrilaterals.

2) Brick - Cuboid; Road Roller - Cylindrical

3) -4, -3, -2, -1, 0, 1, 2, 3 and 4

4) -250 + 150 = (-100)

5) 137 + (-354) = 137 - 354 = (-217)

6) A day = 24 hours, thus, 6 hours are 6/24 = 1/4 of a day

7) (number not given... sorry)

8) (value of s not given... sorry)

9) (whose equivalent fraction is needed to be found is not given... sorry again)
