Which represents the solution(s) of the system of equations, y = x^2 – 4x – 21 and y = –5x – 22? determine the solution set algebraically. (–1, –17) (1, –27) (–1, –17) and (1, –27) no solutions

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
