The slope of a linear line can be found using the equation:

m=(y2-y1)/(x2-x1)

m=(2 - -6)/(9 - 3)

m=(-4)/(6)

m=(-2/3)

The area of the square adjacent to two sides of a right triangle are 29.25 square units and 13 units 30 POINTS

Answer:

$x=6.5\ units$

Step-by-step explanation:

step 1

Find the length side of the smaller square

The area of the square is equal to

$A=a^{2}$

$a^{2}=13$

$a=\sqrt{13}\ units$

step 2

Find the length side of the larger square

The area of the square is equal to

$A=b^{2}$

$b^{2}=29.25$

$b=\sqrt{29.25}\ units$

step 3

Find the value of x

Applying the Pythagoras Theorem

$x^{2} =a^{2}+b^{2}$

substitute the values

$x^{2} =13+29.25$

$x^{2} =42.25$

$x=6.5\ units$

Find a whole number between 9 4/9 and the square root of 144

postnew [5]

First, we'll want to write out the equation
$9 \frac{4}{9} < n < \sqrt{144}$

then reduce what we can
$9 \frac{4}{9} < n < 12$

so this means n can equal any whole number between 9 4/9 & 12, which gives us the options of {10,11}

$n = 10 \: or \: 11$
