Answer:
268 cm
Step-by-step explanation:
A P E X
Answer:
Yes
Step-by-step explanation:
Because since it tells you that x>7 and also it tells you if 7.1 is a solution. So what you need to do is plug in 7.1 instead of x and see if it's true or not. So is 7.1 greater than 7. Well yes it is and that makes it a solution. Hope this helps. Ask me any question if you need help with anything else. :)
Answer:
B because they are basically the same AB = 2, there was no change, just a relfection, so A'B' = 2 as well Hope this helped

Answer:
$8 per lirt
Step-by-step explanation:
if the cost per lirt is $8, the $ per hab will be the same. At x = 8, you can see that the two lines intersect
If you mean "factor over the rational numbers", then this cannot be factored.
Here's why:
The given expression is in the form ax^2+bx+c. We have
a = 3
b = 19
c = 15
Computing the discriminant gives us
d = b^2 - 4ac
d = 19^2 - 4*3*15
d = 181
Note how this discriminant d value is not a perfect square
This directly leads to the original expression not factorable
We can say that the quadratic is prime
If you were to use the quadratic formula, then you should find that the equation 3x^2+19x+15 = 0 leads to two different roots such that each root is not a rational number. This is another path to show that the original quadratic cannot be factored over the rational numbers.
