-. Mrs. Jones has a local bakery. Last week this expression shows how many peanut butter
cupcakes she baked. 5 (2x-4) + 3(3+4x)
irt A: What is the simplified form of the expression above?
irt B: If x = 6, how many cupcakes did Mrs. Jones bake last week?

A) 22x-11

B) 121 cupcakes

Step-by-step explanation:

The expression that shows how many peanut butter

cupcakes she baked is 5 (2x-4) + 3(3+4x).

To simplify this, we need to use the distributive property:

We expand using the distributive property to get:

We group similar terms on the right to obtain:

Combine similar terms on the right to get:

Therefore the simplified expression is

B) We want to find how many cupcakes Mrs Jones baked last week, when x=6.

We substitute 6 into the simplified expression for x to get

Therefore she baked 121 cupcakes last week.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
