Please help! :(( The one I need help in is "What is the equation after you factor the binomial?"

see below

Step-by-step explanation:

this is difference of the squares a² -b² =(a-b)(a +b)

a² =1/9 x² → a = √1/9x² =1/3 x

b² =25 → b = √25 = 5

finally 0 = -1 (1/3x -5)(1/3x5) or

i dont know

step-by-step explanation:

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
