<u><em>Answer:</em></u>
<u>The two correct options are:</u>
The first term, 5x³, can be eliminated
The exponent on the first term, 5x³, can be changed to 2 and then combined with the second term, 2x²
<u><em>Explanation:</em></u>
The degree of an expression is given based on the highest power in the expression
<u>The given expression is:</u>
5x³ + 2x² + 7x - 3
We can note that the highest power in the given expression is 3 which means that <u>the degree of the expression is 3</u>
<u>A quadratic function</u> is a function of <u>degree 2</u>. This means that the highest degree in the expression (function) must be 2
Accordingly, Martha should get rid of the term with power 3 (5x³) in her equation
<u>This can be done by 2 methods:</u>
1- She simply eliminates the term with the third degree
2- She changes the degree of the term with degree 3 to a lower degree and combines it with any existent like term
<u>Comparing the above with the given options, we can conclude that the two correct options are:</u>
- The first term, 5x³, can be eliminated
- The exponent on the first term, 5x³, can be changed to 2 and then combined with the second term, 2x²
Hope this helps :)
The LCM is the lowest number that is a multiple of all three numbers.
First, list the multiples of each number
8: 8, 16, 24, 32,40 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
10: 10, 20, 30 40, 50, 60, 70, 80, 90, 100, 110, 120
12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120
The LCM is 120 because there is no lower number that is a multiple of all three numbers.
Hope this helped!
(3x+2) (x-7)
FOIL
first 3x*x = 3x^2
outer 3x*-7 = -21x
inner = 2*x = 2x
last 2*-7 = -14
add them together = 3x^2 -21x+2x -14
combine like terms 3x^2 -19x -14
I think the one you chose is correct but I am not sure tho
