Answer:
A. 72cm
Step-by-step explanation:
Figure a is a convex pentagon, a convex pentagon is a pentagon that does not have an internal angle greater than

An easier thing to remember is that it does not have an angle pointing inwards like b, none of its angles/edges point toward the shape/inside
Answer:
Where is the picture of the triangle?
Answer:
(7, 5) no
(-6, -3) yes
(-5, 2) no
(1, -4) no
Step-by-step explanation:
For this question we have to input the x and y values into the equation: 2x - 9y = 15
For (7, 5) we would get 14 - 45 = 15 which is false so it is not a solution.
For (-6, -3) we would get -12 + 27 = 15 which is true so it is a solution.
For (-5, 2) we would get -10 - 18 = 15 which is false so it is not a solution.
For (1, -4) we would get 2 + 36 = 15 which is false so it is not a solution.
Answer:
21
Step-by-step explanation:
Three raise to third power can be written as
. In this three is the base which is raised to third power.

Next we need to subtract 6 from Three raise to third power(i.e from 27)
which can be written mathematically as

Hence 6 less than three raised to the third power is 21 as explained above.
