Find the approximate length of the hypotenuse of a right triangle with leg lengths 8.4 cm and 7.6 cm.

11.33 cm

Step-by-step explanation:

hypotenuse² = 8.4² + 7.6²

                     = 70.56 + 57.76

                    =      128.32

hypotenuse = √128.32   = 11.33cm

3rd box is the answer

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
