If you would like to simplify (3 * x + 5) + (2 * x - 9) - (4 * x + 3), you can do this using the following steps:

(3 * x + 5) + (2 * x - 9) - (4 * x + 3) = 3 * x + 2 * x - 4 * x + 5 - 9 - 3 = 1 * x - 7 = x - 7

The correct result would be x - 7.

A rectangular piece of tin has an area of 1056 square inches. A square of 3 inches is cut from each corner, and an open box is m
kvv77 [185]

Answer:

44 inches and 24 inches

Step-by-step explanation:

Let l,b denotes length and breadth of a rectangle.

lb=1056

A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides.

New length =l-6 inches

New breadth =b-6 inches

Height of box =3 inches

Volume of box = length × breadth × height

(l-6)(b-6)3=2052

lb-6l-6b+36=684\\6(l+b)=408\\l+b=68\\b=68-l

Put b=68-l in lb=1056

l(68-l)=1056\\l^2-68l+1056=0\\l^2-44l-24l+1056=0\\l(l-44)-24(l-44)=0\\(l-24)(l-44)=0\\l=24,44

At l=24,b=\frac{1056}{24}=44 inches

At l=44,b=\frac{1056}{44}=24 inches
