Answer:
Step-by-step explanation:
The expression, written in full, looks like this:
To simplify this expression, it would help us out a lot if we could factor the expressions in the denominators. Let's handle 
first:
Next, we can factor 
:
Substituting these back into our original expression, we get
On the left, we can cancel an (x+3) in the numerator and denominator, and on the right, we can cancel an (x-4), simplifying the expression to
Multiplying the two together gives us the fraction
Since 
, we can rewrite this fraction in simplified form as
Answer:
In graph
Step-by-step explanation:
First put it in Slope -Intercept form.
then graph the y- intercept first.
After that it's rise over run so think 1/1
up 1 over one.
Answer:
$21.25
Step-by-step explanation:
25 decrease 15% =
25 × (1 - 15%) = 25 × (1 - 0.15) = 21.25
The second one is equal to each other regardless, if you cancel the 2x you get 12 = 12
Answer: 24
15/5=x/8
Step-by-step explanation:
The triangles are similar and the right hand triangle is 3 times larger than the other.
Similar because two angles are equal so the third is also. One angle is marked as equal, and one is formed by intersecting lines and so is equal to the corresponding angle.
