20 because 19 16/33 is the exact answer. Since they ask about how much that can be rounded up to 20
Answer:
1/2
Step-by-step explanation:
(1/16)^x
Let x = 1/4
(1/16)^ 1/4
Rewriting 16 as 2^4
(1/2^4)^ 1/4
We know that 1 / a^b = a^-b
(2 ^ -4)^ 1/4
We know that a^b^c = a^(b*c)
2^(-4*1/4)
2^-1
We know that a^-b = 1/ a^b
2^-1 = 1/2^1 = 1/2
Answer:
44cm^2
Step-by-step explanation:
（a+b)h/2
=(9+13)4/2
=22x4/2
=88/2
=44
The Area is 44 cm^2, so it's the first choice.
Answer:
-4
Step-by-step explanation:
Because when distrubuting first you distribute 2(-5) which gives you -10 and then you distribute 2 into 3 which is 2(3) which gives you 6. So now you have -10+6. So you can further simplify that into -4. We get -4 because -10 + 6 is -4. And the 4 is negitive because there are more negitives than positives.
