First of all , you need to find the area of both walls and then add them together to get the amount of square feet in one wall. You also have to multiply the answer by 2 to get the square feet that need to be painted.
19*15=135 --> 135*2= 270
8*10= 80 ---> 80*2= 160
once you have done this you add 160+270, and you get your which is yes, because there is only 430 squared feet that need to be painted.
89/100 as a precent is is 89% because if you change 89/100 to a decimal you get .89 and then you multiply that by 100 (or just move the decimal over 2 places to the right) and you will get 89% make since? and its the same way if your going from % to decimal except you divide by 100( or move the decimal over 2 places to the left) so to a percent is right and to a decimal is left. easy right?

Answer:
any number that satisfies this equation is imaginary.
Step-by-step explanation:
if you take the square root of both sides to find x, you will get a negative 1 in the house. You can't have a negative number in the house, therefore, any number that satisfies this equation is imaginary.
