A. 4.0
b. 16.0
c. 12.5
d. 11.7

D

Step-by-step explanation:

to find the answer you do the square root of (x2-x1)^2+(y2-y1)^2.

So you just plug it in and get the equation of

the square root of (-4-2)^2+(-8-2)^2 which equals 11.66190379

then you round to the tenths which then comes out to 11.7

D. 11.7

Step-by-step explanation:

= √(−4−2)^2 + (−8−2)^2

= √(-6)^2 + (−10)^2

= √36 + 100

= √136

= 11.66 which rounds to 11.7

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!
