In the figure, cd = ef and ab = ce. complete the statements to prove that ab = df.
cd + de = ef + de by the (a. addition b. subtraction c. substitution d. transitive ). property of equality
ce = cd + de and df = ef + de by ( a. addition b. subtraction c. segment addition d. transitive )
ce = df by the ( a. addition b. subtraction c. substitution d. transitive) property of equality.
ce = df by the ( a. addition b. subtraction d. substitution d. transitive) property of equality.

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.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
