The greatest common factor is 5
Answer:
312
Step-by-step explanation:
Triangles
1/2 12 *10 = 6*10 = 60
there are two triangles meaning we have to multiply 60 by 2 = 120
Rectangle
12*16 = 192
Add the two and you have the area 120+192=312
2x+10=0
subtract 10 from both sides
2x=(-10)
divide 2 from both sides
x=-5
