Answer:
We know that a negative value is positive of all even exponents and negative for all odd exponents.
y=(-1)^x
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.
For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.
Area of square = 5 x 5 = 25
area of trapezoid = 1/2(2+5)(4) = 28/2 = 14
area of figure = 25 + 14 = 39
answer
39 in^2
Answer:
C
Step-by-step explanation:
the area (A) of the hexagon can be calculated as
A = 
pa ( p is the perimeter and a the apothem )
p = 6 × 10 = 60 and a = 5
, then
A = × 60 × 5
= 30 × 5
= 150
≈ 259.8 cm² ( to the nearest tenth )
