The length would be 230, and the width would be 170, and since there are 4 sides there would be 2 of each. So 230x2=460 and 170x2=340. 460+340= 800
7b^2 - 19b + 10
(b - 2)(7b - 5)
b1 = 2 ; b2 = 5/7
JK is perpendicular to LM
∠LNK = 90°
∠MNJ = 90°
Answer:
x + 10 = x
Has no solution because when you simplify it, you get
10 = 0 which is a false statement
2x + 4 = 2x
Has no solution
Because if reduces to 4 = 0
