x = # of points scored in the first half of the game
35 - x <---- This expression tells us how many points Leah scored in the second half of the game.
Leah scored 17 points in the second half of the game, let's set our expression equal to 17
35 - x = 17
Subtract 35 from both sides
-x = -18
Divide both sides by -1
x = 18
Leah scored 18 points in the first half of the game.
Answer:
132
Step-by-step explanation:
Divide it into 2 shapes : a triangle and a rectangle.
The triangle's base length is 20-(8+6) = 6
The height is 10-6 = 4
The triangle's area = 6*4/2 = 12
The rectangle's area is 6 * 20 = 120
Add the two together, and you get 12+120 = 132
