The diagram shows changes of state between solid, liquid, and gas, The atoms of a substance lose energy
during a change of state. After the change, the atoms are
clase together but are able to slide past one another.
Which arrow represents the change of state described
above?
OL
gas
OP
solid
liquid
Q

answer: 1 and 3

step-by-step explanation:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

step-by-step explanation:

the true ones are a b and d

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
