<span>2x-1=4(x+1) Given. This is the expression you were originally given. 2x-1=4x+4 Distributive Property You distributed the 4 in the subexpression 4(x + 1) to make 4x + 4 2x=4x+5 Addition or Subtraction Property of Equality You added 1 to both sides of the equation. â’2x=5 Addition or Subtraction Property of Equality You subtracted 4x from both sides of the equation. x=-5/2 Multiplication or Division Property of Equality You divided both sides by -2.</span>

Answer:

2x - 1 = 4(x + 1)      Given

2x - 1 = 4x + 4       Distributive Property

2x = 4x + 5           Addition or Subtraction Property of Equality

-2x = 5                  Addition or Subtraction Property of Equality

x = -5/2                Multiplication or Division Property of Equality


- I took the test, these should be right.

In the 30-60-90 triangle below, side s has a length of _____ and side q has a length of _____.
Slav-nsk [51]

In a 30-60-90 triangle, the side lengths are in the ratio 1:2:sqrt(3) = short leg: hypotenuse: long leg.

We know the hypotenuse is 8. We can use this to find the other legs.

The short leg s is 8/2 = 4 because the short leg is always half of the hypotenuse.

The long leg q is 4 * sqrt(3), because the long leg is always sqrt(3) times the shorter leg.

So:

s = 4

q = 4 * sqrt(3)

KM bisects ∠LKJ. If m∠LKM = 4x + 12 and m∠MKJ = 6x - 6, find the value of x. *
riadik2000 [5.3K]

Given that,

KM bisects ∠LKJ.

m∠LKM = 4x + 12 and m∠MKJ = 6x - 6

To find,

The value of x.

Solution,

As KM bisects ∠LKJ. It would mean that,

m∠LKM = m∠MKJ

Putting the above values,

4x+12=6x-6

We can solve the above equations as follows :

4x-6x=-12-6

-2x=-18

x=9

Therefore, the value of x is equal to 9.
