How do you work out this problem? 3x3 + 2x2 + 3x+2 I showed three different people my work an they said I did it wrong I am so confuse.
If it takes 54 mL of 0.1 M NaOH to neutralize 125 mL of an HCI solution, what is the concentration of the HCI?
if you dissolve 350 g of K(2)CrO(4)in 2.4 kg of water, what is the molality of the solution?
Dressmaking and Design
I need to see if my answers are correct on a couple of questions. 1. It's especially important to avoid stitching across the seam allowances when sewing a a. patch pocket with straight edges b. corner that has a seam c. point that has no seam d. curved-seam pocket I think ...
A hockey puck is sliding on frictionless ice. It slams against the wall and bounces back toward the player with the same speed that it had before hitting the wall. Does the velocity of the hockey puck change in this process? Explain.

suppose that oil spilled from a tanker and spreads in a circular pattern whose radius increases at a constant rate of .5 feet per second. -find a function f that models the radius of the oil spill as a function of time r=f(t) with t measured in seconds. How long before the rad...
Physics: Aluminum Block
A 1.65-kg aluminum block and a 6.85-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle è = 31.0°) as shown in the figure. Making use of the table below, determine the ...
A boy coasts down a hill on a sled, reaching a level surface at the bottom with a speed of 6.2 m/s. If the coefficient of friction between the sled's runners and snow is 0.060 and the boy and sled together weigh 480 N, how far does the sled travel on the level surface befo...
