The answer is (2b+1)(3b-4)
At least 680 in sales because 200$-64$ is 136. 136*5=680 because 136 is one fifth or 20% of 680
Given:
two pieces of wood that are 5 feet long each.
form a triangle with a perimeter of a whole number.
third side the triangle will be the house
Since two sides are already of the same length, he can create an isosceles triangle.
An isosceles triangle has two equal sides and two equal angles.
Assuming that the 3rd side is also 5 feet long, then, he can create an equilateral triangle.
An equilateral triangle has three equal sides and three equal angles, measuring 60° each angle.
A scale factor of 3 was used, because Figure B's measurements are 3 times Figure A's measurements.
Hope that helped!
