Answer:

41 units

Step-by-step explanation:

Rectangles have right angles, so we can use Pythagorean theorem to find the diagonal.

c² = a² + b²

c² = 9² + 40²

c² = 81 + 1600

c² = 1681

c = 41

(-12,-5);slope =1/3 write in slope -intercept form​
leonid [27]

Answer:

y = \frac{1}{3} - 1

Step-by-step explanation:

y - y1 = m (x - x1)

y + 5 = \frac{1}{3} (x + 12)

y + 5 = \frac{1}{3} x + \frac{12}{3}

y + 5 = \frac{1}{3} x + 4

y = \frac{1}{3} x - 1

Hope this was helpful :)

Answer:

56 + 23 + (-5)

you want to expand the bracket first

23 + (-5)

23-5 = 18

56 + 18 = 74

a) 74

6 + 24 + (-2)

24 - 2= 22

6 + 22 = 28

b) 28

3 + 7 + (-42)

7 - 42 = -35

3 - 35 = -32

c)-32

( 8 + 1 ) + (-3)

+(-3) = -3

9 - 3 = 6

d)6

( 7 + 10 ) + ( 3 + 1 )

17 + 4 = 21

e)21

59 + 2+ (-6)

2+(-6) = 2-6 = -4

59-4

55

f)55

41 + ( -89)

41 - 89

= - 48

g)-48

( - 13) + 33

-13+33

= 20

h) 20
