Factor the expression using the GCF 100-80

The prime factorization of 100 is: 2 x 2 x 5 x 5.

The prime factorization of 80 is: 2 x 2 x 2 x 2 x 5.

The prime factors and multiplicities 100 and 80 have in common are: 2 x 2 x 5.

2 x 2 x 5 is the gcf of 100 and 80.

gcf(100,80) = 20.

Step-by-step explanation:

PLEASE MARK ME BRAINLIEST

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.
