D
Step-by-step explanation:
1/25 is the same thing as . So, u wantn to find whcih answer choice does not equal that. You can use the exponent multiplication rule, where x^a times x^b equals x^a+b.
for example, answer choice A would be 5^(3+-5) which is 5^-2.
the only choice that does not equal 5^-2 is D because it equals 5^2
Answer:
Step-by-step explanation:
To add two fractions we need a common denominator. Just by looking at the two, there are no common factors. This means the denominator would be the product of the two: 4x(x-8). In order to obtain this, we multiply the first fraction by (x-8)/(x-8) - 1, and the second by 4x/4x - 1:
We can use the distributive property to simplify:
The sum of the two is:
Answer:
Step-by-step explanation:
take angle C as reference angle
using tan rule
tan C=oppposite/adjacent
tan C=6/12
tan C=0.5
C=0.5
C=26.6 degree
