Please help me, I have no clue what its asking and I have to explain it in class tomorrow morning

Nat2105 [25]

Answer:

The term was obtained by grouping and adding the all x terms in the expression.

Step-by-step explanation:

The example has already provided this step:

(x -4) +(x +1) +(¼x +5)= $\frac{9}{4} x + 2$

Thus, the question is asking how is $\frac{9}{4} x$ derived from the expression.

The attached picture shows the intermediate working to arrive at the final perimeter expression.

This expression is later equated to 20 since it is given that the perimeter of the traingle is 20 inches.

It takes Adara 3 hours to drive from Ashdown to Bridgeton at an average speed of 60 mph.

Scrat [10]

Answer:

61.2 mph

Step-by-step explanation:

Let's first calculate the individual legs of Adara's trip in terms of both time and distance:

Ashdown to Bridgeton

3 hr at 60 mph = 180 miles in 3 hours

Bridgeton to Carton

30 miles at 70 mph: 30 miles/(70 miles/hour) = 0.429 hours

Total Trip

Miles = 180 + 30 = 210 miles

Time = 3 + 0.429 = 3.429 hours

Average speed is (210 miles)/(3.429 hours) = 61.25 or 61.2 miles/hour to 1 decimal point.
