Use pemdas (9 - 6)^2 - (48 divided by 8) steps

Step-by-step explanation:

1) Simplify 9 - 6 to 3.

2) Simplify 3² to 9.

3) Simplify 48 ÷ 8 to 6.

4) Simplify.

Therefor, the answer is 3.

3

Step-by-step explanation:

Subtract 6 from 9

- (48 ÷ 8)

Divide 48 by 8

- 6

Raise 3 to the power of 2

9 - 6

Subtract

3

good luck, hope this helps :)

b, i believe, but not sure.

< 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)
