1. Simplify= xy^3 2. Factorise= (2x+1)(2x-1) 3. 4. 5. Estimate= 415.96 6. Highest Common Factor 70= -70,-35,-14,-10,-7,-5,-2,-1,1,2,5,7,10,14,35,70 98= -98,-49,-14,-7,-2,-1,1,2,7,14,49,98 7. Expand: 4-4x+x^2 Simplify: x^2-4x+4 8. 9. This is actually the easiest you take both the mass and volume and divide them :) which would be 500g<span>÷25cm^3=20g/cm3 </span> 10.
The ones I didn't answer I am not sure about and don't wanna give you any wrong answers :) Hope I helped though!
So we know that 2 cities are 5.75 inches apart on the map and the scale reads for every 0.5 inch its 30 miles. So we can first start of by diving 5.75 by 0.5, since we need to know how many “0.5” inches are in 5.75 inches. You’d get 11.5. Now 11.5 multiply that by 30 which would get you 345 miles.
