Question

Evaluate the expression when
=a8
and
=b5
.
−40ab

Answer 1

Do you mean when a = 8 and b = 5?

Answer 2

yes

Answer 3

we solve this problem the same as the last one :) remember? 40-8*5

Answer 4

If you have -40ab, and a = 8, and b=5, just plug in 8 for a and 5 for b into the expression and simplify.

Answer 5

I think it's 40-ab it keeps messing up the format like last time :) @StudyGurl14

Answer 6

So...
\(\large -40ab\rightarrow-40(8)(5)\rightarrow ?\)

Answer 7

oh, it is? sorry 'bout that.

Answer 8

Same thing though, just plug in those values into 40-ab.

Answer 9
