$9 {t}^{2} + 42 t + 49 = {\left(3 t + 7\right)}^{2}$
Notice that $9 {t}^{2} = {\left(3 t\right)}^{2}$ and $49 = {7}^{2}$ are both perfect squares, so it remains to check whether the middle term is correct:
${\left(3 t + 7\right)}^{2} = {\left(3 t\right)}^{2} + 2 \left(3 t\... | {} |

9-127.
Without a calculator, simplify each of the following expressions.
1. $0.25 + 2.5 + 2.5$
Try doing this one without making any calculations on paper. What is $2.5 + 2.5$?
2. $432.7 - 0.08$
Here, you are subtracting $\frac{8}{100} \text{ from }432\frac... | {} |
