Answer: 5x - 2
Step-by-step explanation:
So area is length*width, we have the area and length which is 5x^2 + 43x - 18 and x + 9. So we need to divide. First the x, what times x is 5x^2? 5x, x*x is x squared. Then we need to apply the 5x to 9. 5x*9 is 45x, and we can’t do anything to the 18 because 18/5 is a decimal. After that we subtract the new area with the old one. 5x^2 + 43x - 18 minus 5x^2 + 45x which is -2x - 18. Now we divide the -18 with 9 which is -2. Remember the 5x we had from using the x? We put that and -2 together which is 5x-2, and that’s your width. Hope this helped!
Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s

circle a and circle b must exist
Step-by-step explanation:is circle a and circle b did not exist this question would not be one
Step-by-step explanation:
The tables rule is y = x²+x. Thus, the three missing boxes from top to bottom are 6, 5, and 2. Two other rows could be x = 13, y = 182, and x = 0, y = 0.
