Answer:
4 + 9x² + 1x³ + 12x⁵
Step-by-step explanation:
3x² + 6x² = (3 + 6)x² = 9x²
4 + 3x² + 8x³ + (-7x³ + 12x⁵ +6x²) = 4 + <u>3x² + 6x² </u> + <u>8x³ - 7x³ </u> + 12x⁵
= 4 + 9x² + 1x³ + 12x⁵
Answer:
For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution. You can solve this as you would any other equation. 13x−5(x−4)=8x+513x−5x+20=8x+58x+20=8x+58x−8x+20=8x−8x+520=5 We see this is a false statement because 20 does not equal 5.

Answer:
4 root 5
Step-by-step explanation:
assume / to be root sign
/10 x /8
simply both roots so that one of numbers is a square number
/10= /2 x /5
/8= /2 x /4
so
/4=2 and /2 x /2= 2
2×2=4 and you have /5 left over so
4/5
hope this helps!
Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
