Answer:

$x = \{13,14\}$

Step-by-step explanation:

Given

$x + 2x + 6 < 50$

Required

True values of x

We have:

$x + 2x + 6 < 50\\$

$3x + 6 < 50$

Collect like terms

$3x < 50-6$

$3x < 44$

Divide both sides by 3

$x < 44/3$

$x < 14.67$

This means that x has a value lesser than 14.67.

Hence, the valid values are:

$x = \{13,14\}$

A square room has a floor area of 81 square meters. The height of the room is 5 meters. What is the area of one wall

VMariaS [17]

Area of a square is side length ^2

To find the length of the side of a square from the area, that’s the square root of the area:

Length of side = sqrt(81) = 9 meters

Area of wall = length of side x height:

Area of wall = 9 x 5 = 45 square meters

Answer: 45 square meters
