The answer to your question is x = 6
Answer:
x=4
Step-by-step explanation:
We can use the leg rule
hyp leg
------- = -----------------
leg part
2+6 x
------- = -----------------
x 2
Using cross products
8*2 = x^2
16 =x^2
Take the square root of each side
4 =x
The answer is B because you would multiply 3 with 2 giving you a total of 6 and then you add the 2 and you get 8
To do this you equate the two and use x for hours.
So your equation looks like this: 100+15x=75+17x. Now move like terms to get 25=2x. The job will be 12.5 hours long to cost the same.
The correct answer is D.D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
You can tell this by the lead term alone. When you mutliply the term outside to the lead term, D is the only one that has that term.
2a^2b^3*4a^2 = 8a^4b^3
D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
