Option d: 
is the correct answer.
Explanation:
The expression is 
We need to simplify the expression, using the product of powers.
The product of powers states that "when multiplying two powers with the same base the exponent values can be added up".
Thus, grouping the same base and adding the exponent values from the expression , we have,
Adding the exponent, we get,
Thus, the simplified expression is
Hence, Option d is the correct answer.
Answer:
Step-by-step explanation:
3*2x=6x, 3*5=10
So, 6x+10+4x = 5x+15
Add 6 and 4 which leaves you with 10x+10 = 5x+15
subtract 10 from 15 and that leaves you with 5 divided by 10x
x=2
Same for second equation
2*8x=16x and 2*3= 6
So 16x-6=16x+28
Add 6 to both sides so you get 34.
Now that 6 is gone you want x on one side so subtract 16x an it leaves you with 0. so X=34

Step-by-step explanation:
Answer: 0.12
Step-by-step explanation: Well since 5/5=1 and in this case 3/5 of 0.2 or
3/5 x 0.2 = 0.12miles of the bridge is finished. to check do 0.2*2/5 since 2/5+3/5=5/5 or the total 0.2miles. so 0.2*2/5 =0.8 and 0.8+0.12= 0.2
