A rectangular carpet is x+5 feet wide and 3x-2 feet long what is the area in square feet of the carpet in terms of x

siniylev [52]

Formula for area:
Area = Wide x Length

Wide: x + 5
Long: 3x - 2

Area = (x + 5) x (3x - 2)
Area = 3x² - 2x + 15x - 10
Area = (3x² + 13x - 10) square feet

on the blueprint of a house, 36 millimeters represents 7 meters.the length of the living room is 27 millimeters on the blueprint

tino4ka555 [31]

36/7 = 27/x.....36 mm to 7m = 27 mm to x m
cross multiply
(36)(x) = (27)(7)
36x = 189
x = 189/36
x = 5.25 m

How many arrangements of three letter can be formed from the letters of the word MATH if anyletter will not be used more than on

Mariulka [41]

Combinations = n! / (n - r)! r!

$C\text{ = }\frac{n!}{(n-r)!\text{ r!}}\text{ }$

n = 4

r = 3

Combinations = 4! /(4-3)! 3! = 24/(1)(6) = 24/6 = 4

Answer:
