HELPPP PLEASE!!Three friends went shopping. They each bought one pair of shoes that cost $20 and 4 shirts that cost x dollars.
1. Write an expression that represents this situation.
2. Simplify the expression.

1.

2.

Step-by-step explanation:

1. Let's just focus on one person at the moment. One of the friends bought a single shirt for $20, and 4 shirts that cost x dollars. Therefore, a single person's expense can be shown as:

Where x is the number of shirts the person bought.

Each of the three friends had the exact same expenses too, so we multiply this by three:

2. Simplifying the above equation just means multiplying each term in the parentheses by the 3 outside it, so 3 times 20 is 60, and 4x time 3 is 12x. Therefore, the simplified expression is:

Hope this helps!

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.
