First, you should try to find the sum of the two legs. Because the triangle is isosceles so the legs (b) are equal, than the sum of the two legs:
41*2 ≤ 2b ≤ 43*2 simplified is: 82 ≤ 2b ≤ 86
But we aren't done, for the perimeter also includes the base of the triangle, which is a. Since we already know the sum of the legs, we simply have to add the base (a) to the legs.
Sum of Legs: 82 ≤ 2b ≤ 86
Base: 26 ≤ a ≤ 28
Perimeter (a+2b): 82+26 ≤ P ≤ 86+28 Which simplified: 108 ≤ P ≤ 114
Answer:
t=0
Step-by-step explanation:
First, we expand everything. The left-hand side is -3(2t) - 1(-3), and we expand it to be -6t+3. The right-hand side is t+t+t+3, and we can reduce it to 3t+3. Now that we have both sides of the equation, we set them to each other.
-6t+3=3t+3 (subtract 3 on both sides)
-6t=3t (add 6t to both sides)
9t =0 (divide by 9)
t=0
M is always positive is not true.
Hope this helps!
