Which is 3 groups of 5
bulgar [2K]

Answer:

Specifically, if we want to think of multiplication as repeated addition, exponentiation as repeated multiplication, and ↑↑ as repeated exponentiation, three groups of five is the way to go. 53 means 5×5×5, not 3×3×3×3×3.

X+8=-2<br><br> O A. x= 10<br> OB. x=-6<br> O C. x=6<br> OD. x= -10
MaRussiya [10]

Answer: option D

Step-by-step explanation:

X+8=-2

    x= -2-8 (you should make x the subject so you switch the +8 to the other

    x= -10                                                                   side which becomes -8)    

so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D

Find the area of the regular figure below:​
Mice21 [21]

Answer:

1,496.49 cm squared

Step-by-step explanation:

The regular figure below is a hexagon.

The formula for the area of a regular hexagon is A = \frac{3\sqrt{3} }{2} a^2. Here a = 24. Substitute and simplify for the area.

A = \frac{3\sqrt{3} }{2} a^2\\A = \frac{3\sqrt{3} }{2} 24^2\\A = \frac{3\sqrt{3} }{2} * 576\\A = 1496.49
