Answer:
f(x) = x² + 7x + 12
Step-by-step explanation:
Given that the zeros are x = - 3 and x = - 4, then the factors are
(x - (- 3)) and (x - (- 4)), that is (x + 3) and (x + 4)
f(x) is the product of the factors, that is
f(x) = (x + 3)(x + 4) ← expand using FOIL
f(x) = x² + 7x + 12
The answer to your question would be
Height=5cm+
(18cm)*(y)
<span>Okay, I'm gonna guess that you meant 1024^(3/5), which is much easier to calculate than the other one. ^_^ First thing to recognize is that 1024 is a power of 2. 2^10 = 1024. However, you also know that 2^10 is the same thing as 4^5 (and you could have gone straight to recognizing 1024 as a power of 4 anyway, but meh), so now you know that the fifth root of 1024 is 4. So now what you have is simply 4^3 instead of 1024^(5/3). And of course, 4^3 is just 4*4*4 = 64. Have fun!</span>
Answer:
x = 65
Step-by-step explanation:
All angles in the triangle equal 180
Set up your formula as
180 = x+75+40
180-75-40=x
65=x
