1 answer:
Veronika [31]3 years ago
4 0

Answer:

x^{4} + x³ - 10x² + 20x

Step-by-step explanation:

expand (x - 2)² and (x + 2)(x + 3) using FOIL

= (x² - 4x + 4)(x² + 5x + 6)

multiply each term in the second factor by each term in the first factor

= x^{4} + 5x³ + 6x² - 4x³ - 20x² - 24 + 4x² + 20x + 24 ← collect like terms

= x^{4} + x³ - 10x² + 20x

For a school art project, Kali has 604 square tiles measuring 1 inch on each side. She plans to use the tiles to completely cove
Crazy boy [7]

Answer:

Kali needs 104 more tiles to completely cover the box.

Step-by-step explanation:

Length of box =  20 in

Breadth of box = 6 in

Height of box= 9 in

Total surface area of box = 2lw + 2lh + 2wh

Total surface area of box = 2(20)(6) + 2(20)(9) + 2(6)(9)

Total surface area of box = 708 sq. in.

Side of tile = 1 in

Area of 1 tile = Side^2 = 1^2 = 1 sq. in

Area of 604 tiles = 604 sq. in.

Area remain uncovered = 708 - 604 = 104 sq.in.

So, Kali needs 104 more tiles to completely cover the box.
