Answer:

18x+21

Step-by-step explanation:

First multiply each equation by 2 since there is 2 sides for both the length and width.

2(2x+3)   2(7x+9)

4x+3         14x+18    

Then combine like terms

4x+14x       3+18

18x              21

In how many map squares did we spot more than 29 plant species
Katena32 [7]

Answer:

10 map squares.

Step-by-step explanation:

We have been given a histogram, which represents the plant species spotted in the animal reserve.

The x-axis represents the number of plant species and y axis represents the number of map squares.

We can see that 0 to 9 species are spotted in 1 map square.

10 to 19 and 20 to 29 plant species are spotted in 2 map squares.

To find the number of map squares that spot more than 29 plant species, we will count number of map squares that spot 30 to 49 plant species as 30 to 49 numbers are more than 29.

We can see from our histogram that 4 map squares spot 30 to 39 plant species and 6 map squares spot 40 to 49 plant species.

\text{Total number of map squares that spot more than 29 plant species}=4+6

\text{Total number of map squares that spot more than 29 plant species}=10

Therefore, 10 map squares spot more than 29 plant species.
