What is the value of the expression when a = –5 and c = –1? The expression is 8(a + 2c)

8(a + 2c) = -56

Step-by-step explanation:

Given that,

An expression : 8(a + 2c)

We need to find the value of the above expression when a = -5 and c = -1.

Put the values of a and c in the given expression.

8(a + 2c) = 8(-5+2(-1))

= 8(-5-2)

= 8(-7)

= -56

Hence, the value of the given expression is -56.
