Answer:

I believe the answer is 519m

Step-by-step explanation:

first you seperate the triangle from the rectangle then solve the area for the rectangle 11.5•34=319  then solve the area for the triangle 16•16=256    

256÷2=128    then add 128+391= 519     i hoped this helped you :-)

Answer:

519 meters square

Step-by-step explanation:

16 x 16 = 256

256 / 2 = 128

11.5 + 34 = 391

128 + 391

100 + 300 = 400

20 + 90 = 110

8 + 1 = 9

400 + 110 + 9 = 519

What is the recursive rule for an=3n+5
inessss [21]

Answer:

Option d is correct.

Step-by-step explanation:

We have given a formula a_n=3n+5

We will put different values of n so, as to get a_n

from the given formula

When n =1  we get

a_1=3(1)+5=8

When n=2 we get

a_2=3(2)+5=11

When n=3 we get

a_3=3(3)+5=14

We can see that next term is 3 more than the previous term

Hence, a_1=8;a_n=a_{n-1}+3

Therefore, Option d is correct.

Anyone??? Need help!!!
yaroslaw [1]

Answer:

x=45

Step-by-step explanation:

We know that this is a right isosceles triangle because it has a right angle (square) and a triangle has to add up to 180 degrees so 90+x+x=180

90+2x=180

2x=90

x=45

The equation for line j can be written as y=2x + 8. Another like k is perpendicular to line j and passes through the point (6,-6
Semmy [17]

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 8 ← is in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}, thus

y = - \frac{1}{2} x + c ← is the partial equation

To find c substitute (6, - 6) into the partial equation

- 6 = - 3 + c ⇒ c = - 6 + 3 = - 3

y = - \frac{1}{2} x - 3 ← equation of line k

What is the length of AB? A(-1,5), B(2,-4)
jek_recluse [69]

Answer:

3 sqrt(10)

Step-by-step explanation:

To find the distance, we use the formula

d = sqrt( ( x2-x1)^2 + (y2-y1)^2)

  = sqrt( ( 2- -1)^2 + ( -4-5)^2)

  = sqrt( (2+1)^2 +(-4-5)^2)

  = sqrt( 3^2 +(-9)^2)

  = sqrt( 9+81)

 = sqrt(90)

= sqrt ( 9*10)

  3 sqrt(10)
