PLS HELP!! 1 through 8, if you answer you don’t have to do them all just at least a few pls

1) 29

2) 64

you can use the explanation below to help find the other 6 problems

Step-by-step explanation:

1) 4(5+6) - 15 = 4 * 11 - 15 = 44 - 15 = 29

2) 8(2+4) + 16 = 8 * 6 + 16 = 48 + 16 = 64

=29

Step-by-step explanation:

4(5+6)−15  answer is 29

3(14-7)-16 answer is 5

10(6-5)-3(9-6) answer is 1

2(8+3)+4^2 answer is 38

8(2+1)^2-4^2 answer is 56

< 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)
