Astore is having a 20% off sale. michael says that he can find the sale price of an item that has regular price of p be evaluating the expression 0.8p. susan says that she can find the sale price for the same item by evaluating the expression p- 0.2p. who is correct?

Both are correct methods because the regular price is p or 1.0p. To find 80%, you can use 0.8p. Or to deduct 20%, you can subtract 20% from the full price.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

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.
