Answer:
a
Step-by-step explanation:
We know that
<span>1 1/8 gallons----------> (1*8+1)/8-------> 9/8 gallons
</span><span>13 1/2 miles----------> (13*2+1)/2-------> 27/2 miles
if 9/8 gallons-------------------> 27/2 miles
1 gallons----------------------> X
X=(27/2)/(9/8)---------> 216/18--------> 12 miles
the answer is 12 miles</span>
Answer:
Step-by-step explanation:
x^2 + 3x + 2 = (x+1)(x+2)
x^2 + 4x + 3 = (x+1)(x+3)
LCM = (x+1)(x+2)(x+3) = (x^2 + 3x + 2) (x+3) = x^3 + 6x^2 + 11x + 6
The simplest answer is 0 if u actrually do the work if u have to sneak a calculator in XD
Answer:
- a=1
- b=1
- c=-4
- x = (-1 ±√17)/2
Step-by-step explanation:
The coefficient of x^2 is "a". That is 1.
The coefficient of x is "b". That is 1.
The constant term is "c". That is -4.
The values of a, b, and c are 1, 1, and -4, respectively.
_____
The solution is ...
x = (-b ±√(b^2-4ac))/(2a)
Filling in the values of a, b, and c, this is ...
x = (-1 ±√(1^2 -4·1·(-4)))/(2·1)
x = (-1 ±√17)/2
