20) Find c if m B = 70°, a = 12
A) 41.1 B) 33.2
C) 38.9 D) 35.1

Find and simplify an expression for the area of five rows of x squares with side lengths of x centimeters.

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
