Answer:</h3>
y = x⁴ +4x³ +4x² +4x +3
<h3>
Step-by-step explanation:</h3>
The coefficients of the offered quartics (in order) have 1, 1, 1, and 0 sign changes, respectively. Descartes' rule of signs tells you this means the first three choices all have one (1) positive real root, so the negative real roots -1 and -3 are not the only ones.
The only possible polynomial is the last one. Synthetic division of that polynomial by roots -1 and -3 leave the remaining factor as x²+1, which has only complex zeros.
The appropriate choice is ...
... y = x⁴ +4x³ +4x² +4x +3
Well, if you do this in reverse
23+17 = 40
40-23 = 17
40 would be your answer.
Answer:
x = 12
Step-by-step explanation:
First you need to use the distributive property.
19 = 9 + 2x - 14
Then you should simplify (9-14)
19 = 2x - 5
+5 +5 (Then add 5 to both sides)
24 = 2x
/2 /2 (Divide by 2 to get x by itself)
12 = x

Answer:
252,000
Step-by-step explanation:
since we know that 5% of 240,000 is 12,000
then we just add 12,000 to the 240,000 for a 5% increase
