A rectangle has a length that is four times as long as it is wide. Four students wrote an expression for the perimeter of the rectangle in which w represents the width.
Anoop:
w+w+ 4 + 4w
Beatrice: 2(w.4w)
Camilla: 10w
Damarius: 2 (4) + 2(w)
Which student's expression is incorrect?
OAnoop
O Beatrice
Camilla
Damarius

a. she will receive a refund of $278.

step-by-step explanation:

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.
