Answer:
<h3>The answer is 243.</h3>
Step-by-step explanation:
To evaluate the expression substitute the values of a , b , c and d into the above expression
a = - 9
b = - 7
c = 9
d = 3
So we have
2cd + 3ab = 2(9)(3) + 3(-9)(-7)
= 2(27) + 3( 63)
= 54 + 189
We have the final answer as
<h3>243</h3>

Answer:
-2/3
Step-by-step explanation:
because this is in slope intercept form, m is the slope, so in this case -2/3 is the slope
parallel lines always have the same slope and different y-intercepts
a parallel line could be y=-2/3 +15
 
        
             
        
        
        
Answer:
n = 15
Step-by-step explanation:
This is a right triangle, and so the Pythagorean Theorem applies:
x^2 + 8^2 = 17^2
Solving for x^2:  17^2 - 8^2 = 289 - 64 = 225, and so x = 15.
n = 15
