1: if a3 + b3 = 18 and a2 – ab + b2 = 9,
so what is the value of a + b?
2: if a – b = 4 and a2 + ab + b2 = 12, what is the value of a3 – b3?

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

The quotient of 15 and a number is 1 over 3 written as an equation

Myra took a picture of the sky one afternoon when two jet airplanes appeared to draw a pair of parallel lines with their vapor trails. the vapor trails from two other jets flying from another direction crossed over the parallel trails. she printed her picture and labeled the angles and lines. assume lines c and d are parallel and 2 measures 98°. which statements are true? check all that apply. 3 = 6 = 98° 3 = 14 = 98° 4 = 8 = 82° 4 = 12 = 82° 5 = 8 = 82°
