Q. Distribute to create an equivalent expression with the fewest symbols possible.21(10x+20y+10z)=
Distribute the fraction: We need to distribute the fraction(21) across each term inside the parentheses (10x+20y+10z).Calculation: (21)(10x)+(21)(20y)+(21)(10z)
Simplify each term: Simplify each term by multiplying the fraction (21) with the coefficients of x, y, and z.Calculation: (21)⋅10x=5x, (21)⋅20y=10y, (21)⋅10z=5z
Combine the simplified terms: Combine the simplified terms to get the final expression.Calculation: 5x+10y+5z
