Answer:
Step-by-step explanation:
Here, we want to solve the given quadratic equation using the quadratic formula
We need to rewrite the equation in the standard form;
-4x^2 + 3x + 5 = 0
we have the value a as -4
value b as 3
C = 5
we then substitute these values into the quadratic formula as seen in the attachment
Answer:
20%
Step-by-step explanation:
Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:
1 × 1.25 = 1.25 units.
Now, to get back to 1 unit, we need to find:
1.25 × ? = 1
? = = 0.80
So, 100% - 80 % = 20%
A 20% decrease.
Not completely sure though.

Answer:
(a+c)b OR it's already on simplified form
Step-by-step explanation:
depending upon what your instructor wants, they may want you to say it's already simplified (which happens sometimes).
HOWEVER, if you know how to factorize (which is essentially un-distributing), you could factor out the b which is common in both.
