Cara evaluated (Negative 4) squared incorrectly. Cara subtracted 2 from 6 incorrectly. Cara multiplied 2 and 4 incorrectly.

Answer 1

the answer is the first one, Cara multiplied only 4 and 7 together and did not multiply 4 and 13

Explanation:

if you look through the question you can see that Cara evaluated the (-4)^2 correctly because a negative multiplied by a negative gives you a positive thus (-4)*(-4)= 16, then next you can see that Cara subtracted 2 from 6 correctly because (6-2)= (4), and last but not least Cara did multiply 2 by 4 correctly because 2*4 or 2(4) =8 so as you can see the answer is the first one
