s is less than or equal to 75
First triangle=bxh/2
=3x4/2
=6in squared
rectangle=l x w
=3 x 10
=30in squared
trapezoid=3+5x2/2
=8in squared
6 + 30 + 8
=44 in squared
Answer:
Find the GCD (or HCF) of numerator and denominator. GCD of 6 and 1 is 1.
6 ÷ 11 ÷ 1.
Reduced fraction: 61. Therefore, 6/1 simplified to lowest terms is 6/1.
Think of when If you cross two lines you get a point where they meet
A point is a solution.
So if the lines never cross, then they would have no point, or A, No Solution
