Answer: True
Step-by-step explanation: A rectangle is a parallelogram with all its interior angles being 90 degrees. A rhombus is a parallelogram with all its sides equal. This means that for a rectangle to be a rhombus, its sides must be equal.

Answer:
39cm
Step-by-step explanation: 19cm+15cm+5cm=39
Explanation:
<u>Question 1</u>
At $5 = $3750 revenue
At $17 = $2500 revenue
Hence, at $5 the revenue is more.
<u>Question 2</u>
Looking at the vertex (maximum point of the curve), we can identify that the company should sell their products at cost of $10 by which they will make a revenue of $5000.
<u>Question 3</u>
Domain lies in the x axis of the graph. Here the domain:
0 ≤ x ≤ 20
Answer:
(4,-1)
Step-by-step explanation:
You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11
+ 7x+3y=25
--------------
After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer. Hope this was helpful! :)
