Answer:
just do the opposite numbers on the left side and do the 2nd function on the right!
Step-by-step explanation:
e. 72.
Let x be the measurement of the 3rd side.
x should be greater that the difference of 2 sides
x should be less than the sum of 2 sides
20 - 15 < x < 20 + 15
5 < x < 35
We can assume that x = 35 the maximum measurement of the 3rd side.
Perimeter = 20 + 15 + 35 = 70. Maximum perimeter.
Among the choices, 72 is beyond the maximum, so it is not a possible perimeter of the triangle.
Answer:
1988.
Step-by-step explanation:
71 x 28
= 71 x 8 + 71 x 20.
= 568 + 1420
= 1,988.
8^2 is 64 and 8^7 is 2097152 and do 64*2097152 which is 134217728.
Hope this helps you with your questions.
