Hi!
<u>Explanation: </u><u><em>This question is about math, and this lesson is about order of operations. I will give you a hint. You had to used PEMDAS, P-Parenthesis should be go first, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. If you use multiply, divide, add, or subtract it should go left to right. First, you had to multiply and divide should go left to right. And it gave us -15+10. And finally, you should add and subtract by left to right. And it gave us -5 is correct answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
Answer: Area =
============================================================
Explanation:
The triangle on the right side is a 45-45-90 triangle
The hypotenuse is 8, so the leg length is
This is the height of the parallelogram. The base is 15 which is always perpendicular to the height, and vice versa.
The area of this parallelogram is therefore,
3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
