Answer 2

Answer:

67

Step-by-step explanation:

We are given the expression:

$wx+4$

and asked to evaluate when w=9, x=7, and y=1.

The expression does not contain the variable y, so we can disregard it.

However, the expression does have the variable x and w. We can substitute 9 in for w and 7 in for x.

$(9)(7)+4$

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, multiply 9 and 7.

9*7=63

$63+4$

Next, add 63 and 4.

$67$

The expression wx+4 when evaluated for w=9 and x=7 is equal to 67.
