Answer:
a (9 - 8 a x)
Step-by-step explanation:
Simplify the following:
3 a - 2 a x×4 a + 6 a
-2 a x×4 a = -2 a^2 x×4:
3 a + -2 a^2 x×4 + 6 a
-2×4 = -8:
3 a + -8 a^2 x + 6 a
Grouping like terms, 3 a - 8 a^2 x + 6 a = -8 a^2 x + (3 a + 6 a):
-8 a^2 x + (3 a + 6 a)
3 a + 6 a = 9 a:
-8 a^2 x + 9 a
Factor a out of -8 a^2 x + 9 a:
Answer: a (9 - 8 a x)
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median<span>" is the "middle" value in the list of numbers.</span>
Q21.
6x-19=3x+32
6x-3x=32+19
3x=51
x=51/3
x=17
total of all these angles will be 360 so put the value of x in above equations the answer for both sides will be 83
now
83+83=166
360-166=194
194/2=97
m1 is 97
Q22.
20x+11=25x-14
25x-20x=11+14
5x=25
x=25/5
x=5
total of all these angles will be 360 so put the value of x in above equations the answer for both sides will be 111
now
111+111=222
360-222=138
138/2=68
m1 is 69
Answerdont know but good luk ;)
