D=sqrt((7-5)^2+(-4-3)^2)
d=sqrt(2^2+(-7)^2)
d=sqrt(4+49)
d=sqrt(53)
d=7.28 units
<span>8.4. To come to this conclusion, one must remember that 1/10 of a number is in essence saying this is 1 out of 10 equally divided portions of a number. This is equivalent to 10%. Multiply the number by the denominator, in this case 10, and you will get the total number.
0.84 x 10 = 8.4 (10% x 10 = 100%). Another way to look at it is to add 0.84 ten times. Either way you should end up with 8.4.</span>
We need a picture. What are the answer choices
