Write each of the following in the indicated base. (a) 1021three to base ten. (b) 534 to base twelve (c) MCMLXII to base ten
Kahlil said that using the equation (a + b)2 = a2 + 2ab + b2, he can find a similar equation for (a - b)2. Examine his argument. (a - b)2 = [a + (-b)]2 = a2 + 2a(-b) + (-b)2 = a2 2ab + b2
How would you write about this topic, being different from anyone else's
need to unscramble this word, christmas theme heernwsmeeit
f(x+1)=8x^2+x-3 f(-x)=8x^2+x-3 work: #1 8(x+1)(x+1)+x-3 then FOIL 8(x^2+x+x+2)+x-3 8x^2+16x+16+x-3 *8x^2+17x+13 #2 8(-x)^2-x-3 8x-x-3 *7x-3 I know on the first one you FOIL but im still getting it wrong?? The second one i thought was simple but im getting it wrong
Umm i dont think you have enough info to answer the question is that one of your choices?
Okay thank you that really makes more since your a lifesaver! Do you know how to do number 2 and 3 that you could walk me through too? I have literally tried them 11 times and it still says they are wrong
f(4b)=4x^2+5x-5 f(x+1)=8x^2+x-3 f(-x)=8x^2+x-3 *I think that the first two use F.O.I.L but i still cant get it
