Rounding to the nearest tenth, which of the following give an overestimate? Choose all that apply.
A. 45.07 × 3.45
B. 19.74 × 5.53
C. 8.16 × 60.29
D. 2.92 × 77.81
E. 32.86 × 10.4

 C. 8.16 x 60.29

Step-by-step explanation:

8.16 x 60.29 = 491.9664

When you round the nearest tenth which is 9, it'll be estimated to a 10. The numbers would then be 492.0 which is a overestimate.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
