answer in simplest radical form.
2. There is a threshold on a person's weight that tells doctors when a person is at a greater risk of death. In men, ages 40 - 49, that threshold weight is represented by h=12.3 squared 3 square root of T, where h is height in inches and T is the threshold weight. If a doctor told a 43 year old man that his threshold weight was 218 lbs what would that man's height be (in the form of feet -inches: Ex: 5 ft 9 in)?

1. A = LW

A =  \sqrt{6}  \sqrt{21}

A = \sqrt{6 \times 21}
\\A = \sqrt{2 \times 3 \times 3 \times 7} 

\\A = \sqrt{3^2 \times 14} 

A = 3\sqrt{14} ~ft^2

What is the slope of the line x+3y=10 ​
Minchanka [31]

Answer:

m = -1/3

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Write equation

x + 3y = 10

Step 2: Convert to slope-intercept form

3y = 10 - x

y = 10/3 - x/3

We see that our slope would be the term -1/3x. Since <em>m</em> is the coefficient of <em>x</em> and our slope, our slope <em>m</em> = -1/3
