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!
First u do 1+3+4 which gives u 8...then divide it from the number 56 which gives u 7..then after do (multiplication) 1*7= £7...then 3*7=£21 and then 4*7=£28....ur answer is £7.00, £21.00 and £28.00.....to check them if it's right u could do 7+21+28 which gives u exactly £56.00...so yap hope this helped u :)
Coin insurance formula is (loss)(limit of insurance / Actual Cash Value x Coinsurance%) = Loss settlement. Now I'm not an expert in this, but if you follow this formula you'll see they will recieve $21093.75. Please tell me if I got it wrong.
