Answer: a) $204 b) $331.50
Step-by-step explanation: a) 17 x 12 b) 17 x 19.5 (Sorry, I can't do a diagram, you have to do it by yourself...)
Dude, it's impossible to solve without the pic
X= 28
explanation: pythagorean theorem
Answer:
1, -6
Step-by-step explanation:
Since there are alike numbers, add them together.
4x+x= 5x
Now the function is: f(x)=
+5x-6
The function is in
+bx+c form.
So find the factors of a x c = b.
Factors of -6(a) that fits (b)5 is (-1,6).
Then you just factor it:
f(x)=
+5x-6
(x-1)(x+6)
x-1= 0 x+6=0
+1 +1 -6 -6
x=1 x=-6
Those are the real zeroes: 1, -6
-2a + 3b = 9 / x 2;
-4a + 6b = 18;
Then, -4a + 6b = 18
+4a - 2b = 3
__________________(+)
We obtain 4b = 21;
b = 21/4;
-2a + 63/4 = 9;
-8a + 63 = 36;
-8a = - 27;
a = 27/8 ;
