Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

From an 18-pound cut of meat, Mr. Rand cuts off steaks weighting 1 pound 15 ounces, 3 1/8 pounds, and 4 1/2 pounds. He divides u
worty [1.4K]

Answer:

\$15.60

Step-by-step explanation:

Mr. Rand initially starts with 18 pounds of meat. After cutting steaks weighing  pound 15 ounces, 3 and 1/8 pounds, and 4 and 1/2 pounds, he will have:

18-1.9375-3.125-4.5=8.4375 pounds of meat left (there are 16 ounces in a pound).

Since he sells patties that measure 9 ounces, convert 8.4375 pounds to ounces:

8.4375\text{ lbs}\cdot 16\text{ oz/lb}=135\text{ oz}

Because each patty is 9 ounces, he can make \frac{135}{9}=15 patties. He sells 3 of them for $3.12, meaning the price per patty is \frac{\$ 3.12}{3}=\$1.04.

Therefore, he makes 1.04\cdot 15=\boxed{\$15.60}
