To determine

To solve the expression $2cd+3ab$

Answer to Problem 7E

  $-26$

Explanation of Solution

Given Information: $a=2,b=-3,c=-1,d=4$

  $2cd+3ab$

Calculation:

Given equation is

  $2cd+3ab$

As given, $a=2$ , $b=-3$ , $c=-1$ and $d=4$ .

Hence putting values of a, b, c and d in the equation-

  $2\times \left(-1\right)\times \left(4\right)+3\times \left(2\right)\times \left(-3\right)$

Solving brackets -

  $-8+\left(-18\right)$

Hence the final answer is,

  $-26$
