3,000 +1,000,000,000,000 +1,500 +1,500+ 1,500+ 499.99 +9,720 +9,720 +189.98 +149.99 +159.99 + 15,000=

answer is 1000000001041.89

30=4x-1x

30=3x

30/3=x

10=x

sin(a+b)=sina*cosb+cosa*sinb

cos(a+b)=cos A*cos B − sin A*sin B

(a+b)^2=a^2+b^2+2ab

there is 3 methods they are

-b+(or)-sqrt of b^2-4ac/2a

or

fatrization method

elimination method

choose ur method which u feel gud

^{sqrt3(8000)=20}

2e*4.5-8+-12=? e=5

9e-20

9*5-20

45-20

=25

sum 849 and78

849+78=927

ok you are right i forget

-x-5=0

x=-5 i forget

but i also did =0
