13. draw fraction models (e. g., a fraction bar divided into equal parts, with
some shaded) to show that 3/4, 6/8, and 9/12 are equivalent fractions.

They are equivalent fractions

3/4 = 6/8 = 9/ 12 this says that when we multiply 3/4 with 2 as both denominator and numerator it comes 6/8 . And when we multiply 3 with this fraction the answer is 9/12 .

I hopeit helped drawing isn't possible here otherwise I had drew it

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

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.
