Think about the problem -6 3/5 - (- 7 4/15) + 2 1/5 A. estimate the answer

b. find the actual answer

c. compare the estimate and the actual answer. is your actual answer reasonable?

please help me... im really struggling on this and my grades are DECREASING

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
