X greater than or equal to -7
Answer:
Option (4)
Step-by-step explanation:
Let x =
= (x)(x)(x)(x)
=
= x⁴
Now we substitute the value x =
x⁴ =
x⁴ = 7
Therefore, Option (4) will be the answer.
x = -9
-3x when x is 3 would be -3(3) = -9
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
Polygon X is similar to polygon.
And Polygon X is three times the size of polygon Y.
So, it becomes,
Hence, perimeter of polygon Y is 27.
Therefore, Option 'C' is correct.
