First, multiply the original number by 10. Then multiply the original number by 2. Add the two answers that you got and you have just multiplied by 12. For Example: 7x12=(7x10)+(7x2) 70+14 84
It means you need to multiply 7 by 14 and then add 1 to the answer.It means you need to multiply 7 by 14 and then add 1 to the answer.It means you need to multiply 7 by 14 and then add 1 to the answer.It means you need to multiply 7 by 14 and then add 1 to the answer.
The two numbers that multiply to get 35 and add to 2 are 7 and -5. When you multiply them (7 * -5), you get -35, and when you add them (7 + -5), you get 2. Thus, the numbers are 7 and -5.

a+b=-7 rearrange: b= -a-7=-(a+7) substitute into: ab=30 -a(a+7)=30 -a^2-7a-30=0 a^2+7a+30=0 x = complex number, therefore there are no two Real numbers that exist that satisfy these two conditions.
its 30 because you add 8 and 7 then add it by itself or multiply it by 2**.**
multiply the number by .7, that is 70 % of that number

One way is to multiply 3 and 7 in order to get 21 and then add 9 to 21 in order to get 30.
