Does anyone know how to solve this?

14.76

Step-by-step explanation:

First find the length of the diagonal across the bottom using the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

12^2+5^2 = c^2

144+25 = c^2

169 = c^2

Take the square root of each side

sqrt(169) = sqrt(c^2)

13 = c

Then find the length of the diagonal across the  middle using the Pythagorean theorem

7^2 + c^2 = d^2

7^2 + 13^2 = d^2

49+ 169 = d^2

218 = d^2

Take the square root of each side

sqrt(218) = sqrt(d^2)

14.76482306 = d

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
