(3, 14)
Step-by-step explanation:
hope this helps and have a nice day!! :)
And also you should try to use Desmos calculator it really helps with these problem/ equations!! you just have to put y = x^2+3x-4 then press enter and on the second one you put y=3x+5 and then it shows you a graph and plus the answer!! :))
notice, just like in any multiplication, you can simply multiply each term of either polynomial times the other, sum them up and then cancel like-terms.
2.50X.08=.2
tax is 20 cents
8 percent =.08 as a decimal. to get the decimal of a percent pretend 8 percent is an 8 with an invisible decimal point at its right. so 8% is 8.0. to get a decimal of a percent, move the point two times to the left, and you will put in a 0 for the blank. so its ._8, where he blank is 0 and so 8%=.08
