Answer:
answer is 4.5
Step-by-step explanation:
i believe that's the length of HD.
I think it would be 450 because 510 - 60 = 450
A system of equations may have a single unknown to varying multiples of unknowns , as much the number of unknowns increases , that much system of equations are also built up , else , it can't be resolved
1. (3x+1)(8x-2) 24x^2+8x-6x-2 24x^2+2x-2
2. (5n-5)(4n+8) 20n^2-20n+40n-40 20n^2+20n-40
3. (7x-2)(x^2-6x-5) 7x^3-2x^2-42x^2+12x-35x+10 7x^3-44x^2-23x+10
4. (5b-2)(3b^2-b+2) 15b^3-5b^2+10b-6b^2+2b-4 15b^3-11b^2+12b-4
I have the last two in a little bit.
