No because they are straight lines, they cannot curve to intersect more than once, think of a capital X.
Answer:
proportional because you can divide 16 and 36 by four and get 4/9
The answer is 400 because u multiply 8 x 10= 80 x 5=400
Answer: 120 beats per 45 seconds
Step-by-step explanation:
First of all, you have to find the area of both triangles:


Or just 16 because there are 2 of the same triangles.
Now you have to find the area of the 3 rectangles.
The two that are in the front are 4*3 (l*h) or 12*2 (because there are 2 congruent rectangles. The area of those rectangles is 24 square mm.
Now you find the area of the back rectangle:
5.7*3 = 17.1
Finally, you add all the found numbers to figure out the surface area.
17.1 + 16 + 24 = 57.1 square millimeters.
