Answer:
a =74,321
b. 41,042,523,288
c. 414,832,917
Step-by-step explanation:
because two odd numbers becomes a even number
5 + 5 = 10 7 + 7 = 14 etc
so in the problem you sent 13 and 15 being odd numver will result in a even number when added
See the attached diagram.
In the right triangle, x is opposite the 23.6 degree angle, and the adjacent side is 250 m. This suggests using the tangent ratio.

Finally, to get the height of the tree, add Sarah's height, 1.5 m.
The tree is approximately 110.7m tall.
k<2(3.5) or simplified k<7
Remember:
a^m * a^n=a^(m+n)
a^-m=1/a^m
8³ x 8⁻⁵=8³⁻⁵=8⁻²=1/8²=1/64<1
Answer: the student is not correct, because 1/64<1, and 8³ x 8⁻⁵=1/64.
