What are the solutions of x^2 + 6x -6 = 10

x=2,-8

Step-by-step explanation:

X^2+6x-6-10=0

x2+6x-16=0

x2-2x+8x-16=0

X(x-2)+8(x-2)=0

(x+8)(x-2)=0

X-2=0 x+8=0

X=2,-8

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!
