Question

(c-d^2) / 7d (if c = 11 and d = 5)

Answer 1

hello

to solve this question, let's simply evaluate the expression

$\begin{gathered} \frac{c-d^2}{7d} \\ c=11,d=5 \end{gathered}$

now let's substitute the values into the expression

$\begin{gathered} \frac{c-d^2}{7d} \\ \frac{11-(5)^2}{7\times5}=\frac{11-25}{35}=-\frac{14}{35}=-\frac{2}{5} \end{gathered}$

from the calculation above, the value of the expression is equal to -2/5
