The area of a square is 16 square units. Since 4 V. 5 2 =16 and (–4) 2 = 16 , both 4 and –4 are square roots for 16. Explain why both square roots for 16, the area of the square, cannot be the length of each side of the square.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
