What is the sum of 3.6 × 103 and 6.1 × 103? answer choices 9.7x10^3 9.7x10^6 97x10^3 97x10^6

  9.7×10³

Step-by-step explanation:

(3.6×10³) + (6.1×10³) = (3.6+6.1)×10³ = 9.7×10³

___

The factor of 10³ can be factored out while you do the sum.

___

A calculator can find the sum for you. A scientific or graphing calculator will have the option to display the result in scientific notation format.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
