If a number is added to its square, the result 132. find the number.

x^2+x=132

x=11

im sorry I cant explain how I got the answer aside from saying 10*10=100 100+10 is 110 so I was like lets try 11

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
