Answer:

Step-by-step explanation:

A midpoint of a line means that each segment connecting from the midpoint to an end is equal. For this problem, this means that AB = BC, as B is the midpoint, and A and B are the ends. Therefore, we can say that:

AB = BC

2x + 6 = 5x - 3

add 3 to both sides

2x + 9 = 5x

subtract 2x from both sides

9 = 3x

divide both sides by 3

3 = x

Plugging 3=x into AB, this means that 2(3) + 6 = AB = 12

Which has the larger area, a square with sides that are x +1 units long or a rectangle with a length of x +2 units and a width o

swat32

Answer:

A. Square

Explanation:

The square with sides: x+1

Has an area of: (x+1)^2

The rectangle with sides: x+2 and x

Has an area of: x(x+2)

So we simplify the square: (x+1).(x+1)= x^2+2x+1

Simplifying the rectangle: x^2+2x

Therefore the square area is larger by one unit.

Hope you get it!

Simply using exponents .Then find the products .

aksik [14]

Answer:

$\sqrt[7]{b^{15}}$

Step-by-step explanation:

=> $b^2*\sqrt[7]{b}$

=> $b^2*b^{1/7}$

Where bases are same, powers are to be added.

=> $b^{2+(1/7)}$

=> $b^ {14+1/7}$

=> $b^{15/7}$

=> $\sqrt[7]{b^{15}}$

suppose a rabbit population of 10 rabbits trippled every 2 months. write an exponential function that represents the population

tangare [24]

Answer:

exponential function that represents the population of rabbits : $10*3^{\frac{x}{2} }$

number of rabbits after 2 years : $10*3^{12}$

Step-by-step explanation:

initially there are 10 rabbits. since the will be trippled every 2 months, i have multiplied it with $3^{\frac{x}{2} }$ . I have divided x by 2 because, here x represents number of months and it will be trippled only AFTER EVERY 2 MONTHS.

variable x: it represents number of months.

two years= 2*12 months

now substitute x= 2*12 in the above function.

number of rabbits after 2 years = $10*3^{\frac{2*12}{2} } = 10*3^{12}$
