Gaira was asked to evaluate the algebraicexpression - 3.8x + 6 when x = - 7.5.

-3.8 (-7.5) + 6 (-7.5)

28.5 + (-45)

(-16.5) What mistake did she make? What is the correct answer?

Sample response: Gaira made a mistake when substituting the value - 7.5 in for x. She multiplied both terms of the expression by - 7.5 when she should have only multiplied - 3.8 by - 7.5. The correct answer is 34.5.

brainliest?

gaira ALSO multiplied 6 by x, when 6 doesnt have 6x.

so the correct answer would be only - 3.8 (-7.5) + 6 which is 34.5.
