Which would be the best method to use to solve the following equations. Explain your reasoning. 1. x^2 - 49 = 0 2. x^2 - 3x - 4 = 0 3. x^2 - 2x - 6 = 0 4. x^2 - 17x + 7= 0 ​

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
