C is the correct answer. A line is proportional if it is a straight line that passes through the origin, and while it does pass through the origin, it isn’t completely straight.
Answer is B. No matter what the x or y will be the result will be 0. Anything multiplied by 0 is equal to 0.
A(b + c) = a*(b + c) = a*b + a*c
You must multiply individual terms and see what it would equal
So first, i like to answer the question first. 17 times 6 = 102. So you can use 1 100 model/block and 2 ones :)
D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.
