Determine an expression that would represent the area of the figure shown.
Alborosie

Answer:

Option A : 15x² + 62x + 63 is the correct answer.

Step-by-step explanation:

Given measurements of the figure are:

5x + 9 and 3x + 7

We have to find the area. We can find the area by multiplying the two expressions.

Area = (5x+9) * (3x+7)

Area = 5x (3x+7) +9(3x+7)

Area = 15x² + 35x + 27x + 63

Area = 15x² + 62x + 63

Hence,

Option A : 15x² + 62x + 63 is the correct answer.

a farmer bought 25 rabbits. The number of rabbits doubles every 6 months. What happens to the number of rabbits in 10 years?​ He
Sever21 [200]

Answer:

it will increase to about 26,214,400 rabbits.

Step-by-step explanation:

the number doubles every 6 months,

first of all we have to convert the 10 yrs to months ,,, which will be 10 × 12 months to get = 120 months in total.

divide 120 by 6 months to get the number of times the rabbits will increase to get the answer as = 20.

so we will have to double 20 times.

there are 25 rabbits now. I n the next 6 months, we will have 25 × 2 = 50...... that is i time.......19 times to go. the numbers will go as follows:

50, 100, 200, 400, 800, 1600, 3200, 6400, 12800, 25600, 102400, 204800, 409600, 819200, 1638400, 3276800, 6553600, 13107200, 26214400.
