When simplifying an expression, you collect and simplify all the like terms. Since 8x and -12 aren’t like terms, you can’t substract 8-12
Answer:
=193.2 cm
Step-by-step explanation:
- Figure out the triangles first
- Area= Base times Height divided by 2
- first figure out one triangle A= (6)(5.2)/2 = 15.6 (brackets means times and the slash means divide
- times it by 2 so you get the area of both triangles (15.6)(2)= 31.2
- Now figure out the rectangles
- Area= Base times Height
- A=(6)(9) = 54
- Then times it by 3 to get the area of all three triangles
- (54)(3)= 162
- Now add 162 and 31.2 and you get 193.2 cm

Answer:
x = 16
Step-by-step explanation:
It's a 30°60°90° triangle.
The side opposite to 30° is 8.
x is the side opposite to 90°
8 * 2 = 16
