2w+2l=60 and l = 3w+2
All we need to do to find width is substitute the length in the perimeter formula with the length formula we have established.
2w+2(3w+2)=60
2w+6w+4=60
8w+4=60
8w=56
w=7
width is 7 feet
Answer: this is only for the first question i think its the second one and the 3rd one i think
3. if there were less than 3 acute angles, the triangle would be either obtuse or right.
Answer:
-6(3x +2) = 2x -5 -20x -7 (use the distributive property )
-18x -12 = -18x - 12 (i combined like terms on the right side of the equation)
at this point I can tell that it's true for any value of x, so they all apply
