Answer:
120
Step-by-step explanation:
if 4 is the height, 6 is length and 20 is with, than it would be an area of 120 we get this by multiplying length times with, or 6 times 20. Hope this helped :D
So, i did this,
7.8*10=70
and then add 12
i got 82
did this help??
412-217
195 units
Just subtract them and that would be the distance I’m pretty sure
2b^2 + 81/2 b + 4
basically 2b^2 + 16b + 49/2 b + 4
= (2b^2) + 16b+49/2b) + (4)
= 2b^2 + 81/2 b + 4
