I need help with this question please!

Option D:

Squares are rectangles

Solution:

To find which statement is true:

Option A: Rhombi are squares

Interior angles of rhombus are not always 90°.

But interior angles of a square are always 90°.

So rhombi are not always squares.

It is not true.

Option B: Parallelograms are rectangles

Interior angles of parallelograms are not always 90°.

But interior angles of a rectangles are always 90°.

So parallelograms are not always rectangles.

It is not true.

Option C: Rectangles are squares

Opposite sides of rectangle are congruent.

All sides of square are congruent.

So rectangles are not squares.

It is not true.

Option D: Squares are rectangles

In square all sides are congruent, so opposite sides are also congruent with four right angles.

In rectangle opposite sides are congruent with four right angles.

Therefore all squares are rectangles.

It is true.

Option D is the correct answer.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

constants mean the stopped points or the points on a graph that nothing is changing, hope this
