Please help! For what value of x must ABCD be a parallelogram? x=?

Vlad1618 [11]

Answer:

$x=3$

Step-by-step explanation:

For a shape to be a parallelogram, the angles that are across from one another have to be equal.

We can now find x by making both equations equal to each other and solving.

$11x+1=13x-5$

Solve.

$11x+1=13x-5\\6=2x\\x=3$

Given: F(x) = 2x + 3, find F(X+h)-f(x) and simplify. 01 02 (2h+6)/h

antiseptic1488 [7]

F(x+h) = 2(x+h) +3= 2x + 2h +3
f(x) = 2x + 5

f(x+h) - f(x) = 2x + 2h + 3- 2x - 3= 2h

[f(x+h) - f(x)]/h = 2h/h = 2
