The square is 7 by 7.
Then x inches are added to one side and subtracted from the other.
(7-x)*(7+x) = 45
x = 2
--> 5 by 9

Find the slope given the following ordered <br><br> 2,-3 and 6,-13

saw5 [17]

You would have to use this equation : y2-y1/x2-x1 = slope

So it would be -13 +3/6-2= -10/4

Simplify it and you get : -5/2

Slope is -5/2

$\sf{| \frac{7}{4} \frac{9}{3} | = a}$

$\sf \: |a| = ad - bc$

$\sf\: |a| = (7 \times 3) - (9 \times 4)$

$\sf \: |a| = 21 - 36$

$\sf \: |a| = \bold{ \blue{ - 15}}$

6.4 cm

Step-by-step explanation:

Area of triangle = 17.28 cm²

$\frac{1}{2}*base *altitude = 17.28\\\\\frac{1}{2}*base*5.4=17.28\\\\base = 17.28*\frac{2}{5.4}\\\\base= 3.2*2\\\\base = 6.4 cm$
