Step-by-step explanation:

G(x) = - x^2 + 10x

a + G(a) = a - a^2 + 10a = - a^2 + 11a or 11a - a^2 or a(11 - a)

1/G(a) = 1/(10a - a^2) = 1/a(10 - a)

Which property is used in the first step to solve this equation?

melomori [17]

Answer:

distributive property

Step-by-step explanation:

we know the distributive property states that the multiplication of a number (in this case, the number 4) by a sum (in this case is a subtraction: x-6) is equal to the sum of the multiplications of that number for each of the terms that belong to the sum:

we have: 4(x-6)

we apply the distributive property, so we have

4(x-6)=4*x-4*6

4(x-6)=4x-24

How many three-digit phone prefixes that are used to represent a particular geographic area are possible that have no 0 or 1 in

Sonbull [250]

Answer:

The number of possible three-digit phone prefixes that are used to represent a particular geographic area is 640.

Step-by-step explanation:

The phone prefixes used to represent a particular geographic area are a 3 digit code consisting of numbers from 0 to 9.

The prefix code are of the form: x x x

Condition: The first or the second place cannot take values 0 or 1.

Then the first place can be occupied by the remaining 8 digits.

Similarly the second place can also be occupied by the remaining 8 digits.

And the third place can be occupied by any of the 10 digits.

So the number of ways to construct a phone prefix for any area is:

$Possible\ number\ of\ phone\ prefixes=8\times8\times10=640$

Thus, the number of phone prefixes possible for any area is 640.

Sauron [17]

Your answer would be B.

The triangles would be congruent, because the lines GH and FI are congruent and the angle H and I are the same, and since the line HI is shared by the two, it would then be SAS.
