Answer:
311 mm^2
Step-by-step explanation:
for bases: 1/2(7*5) * 2= 35
for sides: 9 * 12 =108 * 2= 216
bottom sides: 12*5= 60
216+60+35 = 311 mm^2
X = 4
Use division divide both sides by 3
3x/3 leaves x
12/3=4
Hope it helps
x=4
There are 377 members because 245 / .65 = <span>376.9. which you would then round that.</span>
Answer:
x = 2
Step-by-step explanation:
3(10 - 2x) = 18
Divide both sides by 3.
10 - 2x = 6
Subtract 10 from both sides.
-2x = -4
Divide both sides by -2.
x = 2
2x1.5 then divide by 3.14
