on the 1st one I'd say it's none of these.

1. AIf you can divide the square root by 4, then you can double the number on the outside, and then add all of them up.2. D3. B4. A

2 is D, 4 is A

#13 you have to reduce your radicals before adding them.#14 they already gave you the sum of all 4 numbers. Just divide the sum by 4#15 Plug in your cordinates and slope in the following equation: y - y1 = m (x- x1)y1= y value of the point x1= x value of point m= your slope Solve this and youve got your equation.#16 This is Scientific notation. Basically move the decimal point the amount of times it is raised by 10ex a: 134 X 10^5= 13,400,000. I moved the decimal point 5 times to the rightex b: .005 X 10^3 = 5. I moved the decimal point 3 times to the right.I hope this has helped you. Thank you for helping review my Algebra 1 and 2 skills over summer vacation before I enter pre-cal and trig. so I'll give you the letter answers to all 4 problems. but to prevent you from *****ing, I will not give them in coresponding order which is #13, 14,15 & 16 respectively, so you still have to figure it out yourself.
