Pls help! math is my worst subject and i hate all this

KL = 10

Step-by-step explanation:

Since K appears to be a point in JL, we need to add the lengths JK and KL and make it equal to the length of JL

2x - 2 + x - 9 = 2x + 8

Then we can solve for x from there

2x - 2 + x - 9 = 2x + 8

3x - 11 = 2x + 8   [Combine like terms]

x - 11 = 8   [Subtract 2x from both sides of the equal sign]

x = 19   [Add 11 to both sides of the equal sign]

So now that we have the value of x, in order to solve the length of KL, we need to put in the value of x into that expression

x - 9 → 19 - 9 = 10

KL = 10

Hope this helps! I apologize if I'm incorrect

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
