Multiply the values of a and c together;
9*30= 270 <— find prime factors of this
270= 3*3*3*5*2
Now find a way to add these factors in different ways to give 33 (b value)
We can try (3*3*2)+(3*5)=?
18+15=33
Now that you know the numbers, break down the b value.
9x^2+18x+15x+30
9x(x+2)+15(x+2) <— make sure the brackets are the same
(9x+15)(x+2) <— check if this expands to the initial answer
Hope I helped :)
Answer:
x = 5 is not in the domain
Step-by-step explanation:
Given
f(x) = ![\frac{4}{x-5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7Bx-5%7D)
The denominator cannot equal zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be, that is
x - 5 = 0 ⇒ x = 5 ← excluded value
Thus the domain is all real except x ≠ 5
Answer:
Letter B the second one
Step-by-step explanation:
If the "some number" is represented by m, then "some number cubed" is m^3. The product of that and 2 is 2m^3. Eight more than that product is
.. 8 +2m^3 . . . . . . . . upper-left selection
Answer and Step-by-step explanation:
We are given:
A side length of 7
An angle of 30.
We will use trigonometric functions to solve for a.
We will use the sine trig function.
![sin(Angle) = \frac{Opposite (Side)}{Hypotenuse (Side)}](https://tex.z-dn.net/?f=sin%28Angle%29%20%3D%20%5Cfrac%7BOpposite%20%28Side%29%7D%7BHypotenuse%20%28Side%29%7D)
![sin30 = \frac{7}{a}](https://tex.z-dn.net/?f=sin30%20%3D%20%5Cfrac%7B7%7D%7Ba%7D)
Multiply a by both sides, then divide by sin30 on both sides.
![a = \frac{7}{sin30}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B7%7D%7Bsin30%7D)
Now, use a calculator and do 7 divided by sin of 30.
We get <em><u>a</u></em> to be:
14
<u>a is equal to 14</u>
