The perimeter and area of a rectangle are calculated as:

\begin{gathered} \text{ Perimeter = 2(length) + 2(width)} \\ \text{ Area = (length})\cdot(\text{width)} \end{gathered}

Now, we can calculate the perimeter of the rectangle as follows:

\text{Perimeter = 2(x+3) + 2(2x+5)}

Applying the distributive property and adding like terms, we get:

\begin{gathered} \text{Perimeter = (2}\cdot x)+(2\cdot3)+(2\cdot2x)+(2\cdot5) \\ \text{Perimeter = 2x + 6 + 4x + 10} \\ \text{Perimeter = 6x + 16} \end{gathered}

At the same way, the area is equal to:

\begin{gathered} \text{Area = (x+3)(2x+5)} \\ \text{Area = (x}\cdot2x)+(x\cdot5)+(3\cdot2x)+(3\cdot5) \\ \text{Area = 2x}^2+5x+6x+15 \\ \text{Area = 2x}^2+11x+15 \end{gathered}

Answers: Perimeter = 6x + 16

Area = 2x² + 11x + 15

I'm having trouble solving this I don't know the steps
Andreas93 [3]

Answer:

x=4

Step-by-step explanation:

21x+6+90=180

First, we need to subtract the numbers.

21x=180-90-6

21x=84

Now, we need to find the value for 1x, so divide the whole equation by 21

84/21

21/21

x=4

Hope this helps!

Wastewater is filling barrels at the rate of 11 quarts per hour. The recycling facility picks up 120 full barrels on each trip,
dalvyx [7]
(1 h)/(11 qt) * (12 qt)/(1 barrel) * (120 barrels/pickup) * (1 day)/(24 h)
.. = 12*120/(11*24) day/pickup
.. = 5 5/11 days/pickup

120 barrels will be filled every 5 5/11 days. Some trips will be 5 days apart, some trips will be 6 days apart.
