Answer:
1536 in^2
Step-by-step explanation:
This is basically asking for the surface area so knowing that is a cube all the sides are equal so one side would be 16(16) which is 256 in ^2. The knowing that there is 6 sides you would multiply it by 6 which is 256(6)= 1536^2
we have that
−4+8−16+32−.....
a1=-2*(-2)-----> -4
a2=-4*(-2)-----> +8
a3=+8*(-2)-----> -16
a4=-16*(-2)----> +32
a5=+32*(-2)----> -64
a6=-64*(-2)-----> +128
a7=+128*(-2)-----> -256
The sum of the first 7 terms of the series is
<span>[a1+a2+a3+a4+a5+a6+a7]-----> [-4+8-16+32-64+128-256]------->
-172</span>

the answer is -172</span>
Given:
She is required to read a total =
hours a week.
Monday she read
hours.
Tuesday she read
of an hour.
Thursday she read 3 hours.
To find:
The total hours does she still need to read in order to get full credit.
Solution:
Total time =
hours a week.
Total time she already read
hours
hours
hours
hours
hours
Now,
Remaining time = Total time - Total time she already read






Therefore, the required time is
hours.
Hey there! :D
-2(k-2)≥-20
Distribute the -2. Multiply -2 by k and -2.
-2k+4≥-20
Subtract 4 on both sides.
-2k≥-24
Divide by -2 and flip the sign, since you are dividing by a negative.
k≤12
I hope this helps!
