Answer:
x^2 + 2x + 1
Step-by-step explanation:
1. collect the like terms.
2. use the commutative property to reorder the terms.
Answer:
282
Step-by-step explanation:
formula
(n x 3 ) + 3
9 x 3 = 27 + 3
30
30 x 3 + 3 = 93
93 x 3 + 3

<span>P(t) = Po(1 - r)^t
P(t) = price after t months --> S
Po = initial price -- P
r = rate as a decimal
S = P(.9)^4
-> = 100(.9)^4
-> = 65.61
(100 - 65.61)/100
34.39/100

The reciprocal of a number is 1/the number.
Assume that the number is y
Now, we will translate the English wordings of the problem into an equation as follows:
y + (1/y) = 4 x (1/y) (multiply both sides by y to eliminate the denominators)
y^2 + 1 = 4
y^2 = 4-1 = 3
y = +/- sqrt(3) = +/- 1.732
Based on this,
either the number is 1.732
or the number is -1.732
Combine the like terms
3b-5a
Or -5a+3b if keeping in a certain order
