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!
The area of an equilateral triangle is the area covered by an equilateral triangle on a two-dimensional plane. An equilateral triangle is a triangle with all sides equal and all angles at 60 degrees. The area of the shape is the number of unit squares that fit inside.
Here, "unit" refers to 1, and a unit square is a square with one side. Alternatively, the area of an equilateral triangle is the total amount of space it surrounds in a two-dimensional plane.
