Gabriel is driving 80 kilometers in one hour. How many kilometers does he drive in 1.5 hours

gogolik [260]

Answer:

He drove 120 km

Step-by-step explanation:

We know that 1 hour of driving is equal to 80 km. We need to find out for 1.5 km. First, we need to know how much km for 1/2 of an hour. Which will be 40, because 80/2=40. Then we add up the 40 to the 80, and we get 120 km in total.

Which is a solution to (x – 3)(x + 9) = –27? x = –9 x = –3 x = 0 x = 6

likoan [24]

Answer:

x = 0

Step-by-step explanation:

Since the product is not equal zero, we need to multiply both parenthesis first:

$(x-3)(x+9) =-27$

$x*x+x*9+(-3)*x+(-3)*9=27$

$x^2+9x-3x-27=27$

$x^2+6x-27=27$

Add 27 from both sides:

$x^2+6x-27+27=-27+27$

$x^2-6x=0$

Factor $x$ out:

$x(x+6)=0$

Apply the zero product:

$x=0,x+6=0$

$x=0,x=-6$

The solutions of the equation are $x=0$ and $x=-6$ .

We can conclude that the correct answer is x = 0.
