after the negative exponents have been eliminated becomes 
Step-by-step explanation:
Given expression 
We have to write expression after the negative exponents have been eliminated and a ≠ 0 and b ≠ 0.
Consider the given expression
We have to eliminate the negative exponents,
Using property of exponents,
we have ,

becomes 
Thus, the given expression
after the negative exponents have been eliminated becomes 
Answer: 9/55
P(1st = red and 2nd = blue)
= (3/11) x (6/10)

= 9/55
To find the probability of something happening,
= (number of desired outcomes) / (total number of outcomes)
If you are finding the probability of more than one thing happening at the same time, you multiply the probability of both things happening together
Answer:
28 units²
Step-by-step explanation:
Assume that your net has the dimensions shown below.
Its area is
2 yellow rectangles = 2(4 × 2) = 2 × 8 = 16 units²
2 grey rectangles = 2(4 × 1) = 2 × 4 = 8 units²
2 green rectangles = 2(2 × 1) = 2 × 2 = <u> 4 units²</u>
TOTAL = 28 units²
The prism's surface area is 28 units².
Answer:
