So our original equations would be..
2y + 2(y - 4) = p \: (perimeter)
y \times (y - 4) = l \: (area)

(a) perimeter in terms of y
y = \frac{p + 8}{4}

(b) area in terms of y
*I'm actually not sure about b.. sorry*

(c) if perimeter = 28, find length
28 \div 4 = 7
7 \times 7 = 49
l (area)= 49

bekas [8.4K]

Answer:

x = 25°

Step-by-step explanation:

The 2 angles are vertical angles and are congruent , then

2x + 100 = 150 ( subtract 100 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25°

Natalija [7]

Answer:

ana spends 2 hours 50 minutes working

Step-by-step explanation:

ana starts working at 2:40 pm and finishes work at 5:30 pm.

Let's bear in mind that there is 60 minutes in one hour.

Ana started 2.40 , the :40 means 40 minutes

While I 5:30, the :30 means 30minutes

The amount of time spent by anna at the working place.

5:30-2:40= 4 hours minus 2 hours, 90 minutes- 40 minutes

= 2 hours 50minutes

ana spend 2 hours 50 minutes working
