There are two triangles (top and bottom) and 3 rectangles.
the area of the three rectangles is 10*12+10*9+10*7=280
Area of each triangle: 1/2 of 12*5=30
area of two triangles: 30+30=60
Total surface area: 280+60=340 m²
Answer:
Step-by-step explanation:
-8-4v=40 add 8 to both sides
-4v=32 divide both sides by -4
v= -8
3v+2v=25
5v=25 divide both sides by 5
v=5
x/2 - 8 = -14 add 8 to both sides
x/2= - 6
-6 * 2= -12
check
-12/2-8=-14
-6-8=-14
-14= -14
-6+n/3= -3 add 6 to both sides
n/3=3
3*3=9
check
-6+9= -3
-3 = -3
Answer:
x = 6
Step-by-step explanation:
