The answer for that problem is z =12+6
        
             
        
        
        
 5 and 6, the value is about 5.48
        
             
        
        
        
Answer:
its an equilateral triangle and so one of the side is 6 
so to find the answer you should multiply one side into 3
                                                                       =3 x side
                                                                        =6 x 3
                                                                        = 18

For this case we must find 35% of 280.
Kerrie gets 10% and then 25%. So:
10% of 280:
280 ------------> 100%
x -----------------> 10%
Where "x" represents the amount given by 10% of 280.

Thus, 10% of 280 is 28.
Now, we find 25% of 280:
280 ------------> 100%
x -----------------> 25%
Where "x" represents the amount given by 25% of 280.

Thus, 25% of 280 is 70.
So we have that 35% of 280 is given by:

So, Kerrie's solution is correct.

Answer:
-4 = ?
Step-by-step explanation:
<u>Step 1:  Substitute -1 for x</u>
7x^3 + 5x^2 - 2 = ?
7(-1)^3 + 5(-1)^2 - 2 = ?
7(-1) + 5(1) - 2 = ?
-7 + 5 - 2 = ?
-4 = ?
Answer: -4 = ?
