Question If C=t-5 and B=t^2+2 , find an expression that equals 2C+2B in standard form. Answer Attemptiout of 2 square

To find an expression that equals $2C+2B$ in standard form, we need to substitute the given expressions for $C$ and $B$ into the equation and simplify.<br /><br />Given:<br />$C = t - 5$<br />$B = t^2 + 2$<br /><br />Substituting these values into the equation $2C + 2B$, we get:<br /><br />$2C + 2B = 2(t - 5) + 2(t^2 + 2)$<br /><br />Expanding the brackets, we have:<br /><br />$2C + 2B = 2t - 10 + 2t^2 + 4$<br /><br />Combining like terms, we get:<br /><br />$2C + 2B = 2t^2 + 2t - 6$<br /><br />Therefore, the expression that equals $2C + 2B$ in standard form is $2t^2 + 2t - 6$.
