Do anyone know how to do this?​
kykrilka [37]

Answer:

1.) x=4

2.) x=14

Step-by-step explanation:

FOR #1:

1.) In order to solve the parallelogram, you must know that each opposite sides must equal...

so KL=JM and KJ=LM

2.) To solve for "x", you must substitute

 KL= 7x-2\\JM=12x-22

so it should end up with...

7x-2=12x-22

3.) Solve the equation with some algebra

7x-2=12x-22\\-5x=-20\\x=4

FOR #2:

1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

(3x+5)+(9x-17)+180=360

as your equation...

2.) Solve with algebra

(3x+5)+(9x-17)+180=360

3x+5+9x-17=180\\12x-12=180\\(\frac{1}{12}) 12x=168 (\frac{1}{12})\\x=14

Help plzzzzz.............
ludmilkaskok [199]

Answer:

a) 3 b) y = 3x + 11

Step-by-step explanation:

a)

In order to find the gradient (slope), find the change in y or change in x (rise/run).

-2 - 2 / 7 - (-5)

-2 - 2 / 7 + 5

-4/12 = -1/3

Now that we know the gradient of line AB is -1/3, take the opposite reciprocal of that to find the gradient perpendicular to line AB.

-1/3 ⇒ 3

b)

Take point C's values and the perpendicular gradient found earlier and substitute them into the point-slope form equation.

y - 5 = 3(x - (-2))

y - 5 = 3(x + 2)

y - 5 = 3x + 6

y = 3x + 11

PLEASE HELP, SOLVE THIS PROBLEM AND GIVE ME THE ANSWER!!!
snow_lady [41]

Answer:

B. -5.

Step-by-step explanation:

fg(x) = (x - 1)(5x^2 + 19x - 3)

= 5x^3  + 14x^2  - 22x + 3

So fg(-4) = 5(-4)^3 + 14(-4)2 -22(-4) + 3

= -320 + 224 + 88 + 3

= -5.
