Pls fast, i need it
.

hints to solve each. partial answer due to lack of time, hope it helps!

Step-by-step explanation:

1)

a) solve ():

5 + 7 - 9 - 6 + 12 - 10 =

. (5 +7-9-6+12-10)

b) use =

c) use = = 2

use = = 2

2)

a) use =

use = = 2

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
