Answer:
Step-by-step explanation:
The correct domain consists of only five integers: {0, 1, 2, 3, 4} It's possible that the customer buys NO melons; that's why we have that 0 in the domain. No customer may buy more than 4 melons; that's why the domain does not include numbers greater than 4. Only whole melons are sold, which is why the domain contains no fractions, no mixed numbers.

Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Answer:
0
Step-by-step explanation:
Try looking at it in 2 ways- left side and right side. On the left side we have -4*5, which equals -20. On the right we have -4-20, which equals -24. so then when we add it all together (not literally) we get -20=-24. Since -20 and -24 obviously do not equal eachother, there is no solution.
