Gwen is sending a box to a friend. the box weights 23.5 pounds. gwen removes a 4.47-pounds book to decrease the shipping cost. what is the new weight of the box?

The new weight of the box is 19.03 pounds.

Step-by-step explanation:

The original weight of the box is 23.5 pounds. When Gwen removes the book, she subtracts the weight of the book from the weight of the box. We can write this as the simple equation 23.5 - 4.47 = 19.03.

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
