Which statement is true? a)all rectangles are squares. b)all parallelograms are rectangles. c)all squares are rectangles. d)all quadrilaterals are rectangles.

The true statement is '' A square is always a rectangle''.

We have to determine the true statement.

According to the question

1.  There are not all rectangles that are square because all four interior angles are equal to 90°.

All four sides are the same length.

2. The four angles are not all 90 degrees, so it is a non-rectangular parallelogram.

3.  A square is defined as a rectangle having four equal sides.

4. All quadrilaterals are not rectangles it is one of the types of quadrilateral in which all four angles are right angles or equal to 90 degrees.

Hence, The true statement is '' A square is always a rectangle''.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is 1/4
