A rectangle has a length of x - 8 and a width of x + 9. Find the area

Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

Evaluate the expression for the given value of the variable 7a - 4a for a =8
