Answer:
Step-by-step explanation:
It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as 
or 
The question asks for positive exponents though so yu don't need to do that.
You also need to know 
so in this case 
so 
Consecutive numbers mean in order from smallest to largest, therefore, 7, 8, 9, would be the answer. 7+8+9=24.
Answer:
Basically, you calculate your ratio and find what its is, but after that, you have to simplify it, giving you 4.
Step-by-step explanation:
<span>Number of flowers = 6
Number of flowers to choose = 3
We need to solve it using permutations:
6!/3!=1*2*3*4*5*6/1*2*3 = 720/6 = 120
The answer is: there are 120 different arrangements using 3 types of flowers out of 6 types available</span>
Answer:
x = -5, 1
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from 
.
-1 and 5 multiply to -5 and add to 4.
The zeros are the factors set equal to 0 and solved.
(x+5) = 0
x=-5
(x-1) = 0
x=1
