Answer:
729
Step-by-step explanation:
3 to the power of 2 means 3 * 3 which is 9. 3 to the power of 4 means 3 * 3 * 3 * 3 which is 81. Finally, 9 * 81 which gives you 729.
Answer:
Area = length * width
112 = (2w+2)*w
112 = 2w^2 + 2w
0 =2w^2 + 2w - 112
0 = w^2 + w - 56
0 = ( w + 8 )( w - 7 )
w+8=0 results in negative measures
w-7=0 --> w = 7
width is 7
length is 16
