Answer:
All squares are rectangles.
Step-by-step explanation:
A square is a rectange with equal-length sides.
A rectangle is a parallelogram with right-angle corners.
A parallelogram is a quadrilateral with opposite sides parallel.
A quadrilateral is any 4-sided plane figure, not necessarily convex. Sides are not necessarily parallel, nor are angles necessarily 90°.
Answer:

Step-by-step explanation:
Given: In a parallelogram ABCD, diagonals intersect at O and ar(ABCD) is
.
We need to find the area of triangle AOB.
We know that each diagonal divide the parallelogram in two equal parts and diagonals bisect each other.
It means both diagonals divide the parallelogram in 4 equal parts.



Hence, the values of ar(AOB) is
.

Hello! answer:
Step-by-step explanation:
6 × 12 = 72
6 × 12 = 72
3 × 12 = 36
3 × 12 = 36
3 × 6 = 18
3 × 6 = 18
72 + 72 + 36 + 36 + 18 + 18 = 252 therefore the surface area would be 252 hope that helps!
Answer:
Quadratic expression
Step-by-step explanation:
5x + 3x^2 − 7
Degree of expression = 2
So it is Quadratic expression
Answer:
Step-by-step explanation:
x^3 = 1/8
Taking the cube of both side
x^3 = 1/(2)^3
(x)^3 = (1/2)^3
Eliminate ^3 from both sides
x = 1/2
