Answer:
x= -74 or -84
Step-by-step explanation:
x^2+3x+37=-7x
x^2+3x+7x+37=0
x^2+10x+37=0
this convert to following

-b= -(10), a= 1, c =37
according to that
x= -74 or x= -84
7x - c = k
7x = k + c
x = k + c /7
Answer:
0.01000188
Step-by-step explanation:
The third term is ...
8C2·x^6·y^2 = 28 x^6 y^2
Putting in the given values for x and y, we get ...
28·3^6·7^2·10^-8 = 1000188×10^-8 = 0.01000188
_____
8C2 = 8!/(2!·(8-2)!) = 8·7/(2·1) = 28
Answer:
(5.6x10^4)x(1.3x10^8) = 7.28 x 10^12
