35 7/9 x 45/1 = 7/1 x 5/1 by dividing both sides by 9 7/1 x 5/1 = 35/1 = 35

35 + 2k = 9k subtract 2k from each side 35 + 2k - 2k = 9k - 2k 35 = 7k divide both sides integers by 7 35/7 = (7/7)k 5 = k check in original equation 35 + 2(5) = 9(5) 35 + 10 = 45 45 = 45 checks out

Yes and it will be an isosceles triangle with 2 equal sides

This is a scalene triangle as it has no equal sides or angles. It is not a right angle triangle.

That would be an isosceles triangle if two sides are the same length.

45% of 35= 45% * 35= 0.45 * 35= 15.75

that's not a triangle

Then it is a scalene triangle

Assuming the numbers are organized as listed below, here is the answer: (98 / 7) x (45 + 35) = 14 x 80 = 1,120 Alternate Possibility: [(98 / 7) x 45] + 35 = (45 x 45) + 35 = 2025 + 35 = 2,060
