<span> B.
b = 20 units and h = 16 units
</span>
<span>walnut= 4.66 pounds
cashew=2.1 pounds
peanuts=8 pounds
Total nuts= 4.66+2.1+8
= 14.76 pounds
each bag contains= 14.76/18=0.82 pounds of nuts</span>
So you would start with removing the parentheses so 6- - 4 would be 6+4 because the double negative and then that would be 10 so 7 times 10 so your answer is 70
An expression equivalent to that given would be 4^8 or also written as four to the eighth power, hope this helped! Please rate my answers.
Work: 4^8 = 4x4x4x4x4x4x4x4
