Answer:
x=3 , x= -2
Step-by-step explanation:
x^2 -x-6 =0
to solve to find the X's we need to factor.
to factor we need to find gcf.
since this problem has no coefficient in front of the x there is no GCF.
So we need to find the multiples of -6
What times What = -6
-3 and 2 = -6
we know x would need to be foiled to create x^2 so x will be in the parenthesis.
(x ) (x )
now we want to put the multiples into parenthesis
(x-3) (x+2)
but we need to set x-3 and x+2 = to 0
the 0 product property.
x-3=0
+3 +3
x=3
x+2=0
-2 -2
x=2
$90.10 is the total because if you multiple 85 x .06 is gives you 5.10 then you add 5.10 to 85.
Answer:
See below
Step-by-step explanation:
√120 is irrational since it cannot be written as a fraction
√36 is rational because it can be written as 6 or -6 which are both rational
7 is rational because it can be written as a fraction (ex. 7/1, 14/2, 21/3, etc.)
10 is rational because it can be written as a fraction (ex. 10/1, 20/2, 30/3, etc.)
148 is rational because it can be written as a fraction (ex. 148/1, 296/2, 444/3, etc.)
781 is rational because it can be written as a fraction (ex. 781/1, 1562/2, 2343/3, etc.)

Answer:
60 inches = 5 feet.
Step-by-step explanation:
12 inches in one foot, 12 x 5 = 60, meaning it would be 68 inches high
