Answer:
a^6
Step-by-step explanation:
when multiplying exponents, add the exponents together. you can distribute to prove it, a^2 is a•a, a^3 is a•a•a so by bringing it together you get a•(a•a)•(a•a•a) which gets a 6 times or a^6
C because when you expand all the numbers, they go in the same order as c has them.
28 degrees. This is because the first angle is 12 degrees, the third is x degrees and the second is 5x. You know that in a triangle the angles add up to 180 degrees so 12 + 5x + x = 180. Then you get 6x =168 and x =28 degrees. (**x being the thrid angle**)
Answer:
a=15
Step-by-step explanation:
By pythagoras' theorem
25²=20²+a²
625=400+a² group like terms
a²=625-400
a²=225

therefore a=15
