Enrique was asked to solve the equation 3(x + 2) = 12. His steps are shown.
Step 1: 3(x + 2) = 12
Step 2: 3x + 6 = 12
Step 3: 3. = 6
Step 4: x = 3
Which statement about his solution is correct?
The problem is worked correctly at each step.
In Step 2 the problem should be 3.x + 2 = 12.
In Step 3 the problem should be 3x = 18.
In Step 4 the problem should be x = 2.

3(x + 2) = 12

3x + 6 = 12

3x = 6

x=2

Step-by-step explanation:

Enrique was asked to solve the equation 3(x + 2) = 12. His steps are

shown.

Step 1: 3(x + 2) = 12

Step 2: 3x + 6 = 12

Step 3: 3. = 6

Step 4: x = 3

Which statement about his solution is correct?

up till step 3

The problem is worked correctly at each step.

In Step 2 the problem should be 3x + 2 = 12.

false

In Step 3 the problem should be 3x = 18.

false

In Step 4 the problem should be x = 2.

true

1.3(x + 2) = 12

2.3x + 6 = 12

3.3x = 6

4. x=2

Step-by-step explanation:

I think ok

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
