x^2 + 3x - 2; -x^2 - 3x + 2andx - 1; 1 - x
(5x + 10)(x + 3) or 5. (x + 2)(x + 3) Check with x = (say) 3 so 5 x 5 x 6 = 150; 45 + 75 + 30 = 150 OK
10 + 10 + 10
20 = 400
The statement 10 plus 21 equals 31 in total. It can also be written as 10 + 21 = 31.
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
5x2=10...take 5 two times..5+5=10
its 10
It is -10.
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
20 divided by 4 multiplied by 2 plus 6 equals 16. 20/4 = 5, 5x2 = 10, 10+6 = 16.
-5*2-3x+4 when x=-1 is -10-3*(-3)+4=-10*9+4=3
18 because, 5x2=10 10+8=18! Your welcome. It's not a problem at all. I love math!
5x2=10
6 + 10 = 16
5x2=10
If the question is writen out "10-5x2+8/2=" then with the correct order of operations it would be "10-(5x2)+(8/2)=". This simplifies to "10-10-+4=". Finally, this comes to "4"
