15. A family is comparing different car seats. One car seat is designed for a child up to and including 30 lb. Another car seat is designed for a child between
(15)b and 40lb. A third car seat is designed for a child between 30 lb and 85 lb,
Ynclusive Model those ranges with compound inequalities. Whicly car seats are
appropriate for a 32-b
child?

step-by-step explanation:

jjj

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

< 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)
