Write this expression in standard form by collecting like terms:

ExtremeBDS [4]

9 (a - b) + 5 (2a - 2b)

mutiply the first bracket by 9

(9)(a)= 9a

(9)(-b)= -9b

mutiply the second bracket by 5

(5)(2a)=10a

(5)(-2b)= -10b

9a-9b+10a-10b

9a+10a-9b-10b ( combine like terms)

Answer : C. 19a - 19b

Find the value of x in the following diagram, 3x + 10 Here, B and D are points of tangency.

SVEN [57.7K]

Given:

The given circle with center at C. The lines AB and AD are tangents to the circle C.

The length of AB is (3x + 10)

The length of AD is (7x - 6)

We need to determine the value of x.

Value of x:

Since, we know the property of tangent that, "if two tangents from the same exterior point are tangent to a circle, then they are congruent".

We shall determine the value of x using the above property.

Thus, we have;

AB = AD

Substituting the values, we get;

$3x+10=7x-6$

Subtracting both sides of the equation by 7x, we get;

$-4x+10=-6$

Subtracting both sides of the equation by 10, we get;

$-4x=-16$

Dividing both sides of the equation by -4, we get;

$x=4$

Thus, the value of x is 4.

For n = 3, what are the possible sublevels?

PilotLPTM [1.2K]

N represents the quantum number. for n = 3, there are 3 possible sublevels that are 3s, 3p and 3d.
There are four sublevels that are s, p, d and f. In s subshell or sublevel there is 1 orbital, in p sublevel there is 3 orbitals, in d sublevel there is 5 orbitals and in d sublevel there is 7 orbitals.
And there are 2, 6, 10 and 14 maximum number of electrons in s, p, d and f sublevels respectively.

son4ous [18]

Hello!

Answer:

w=12

*The answer must have a positive sign.*

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

$-5+\frac{w}{3}+5=-1+5$
