What are the properties used to solve 4(x+3)=20

ryzh [129]

Answer:

Multiproperty

Step-by-step explanation:

To solve this problem, we use different properties to arrive at our answer.

Given expression;

4(x + 3) = 20;

First we use the distributive property to expand;

4x + 12 = 20

Now use subtraction property by adding (-12) to both sides;

4x + 12 + (-12) = 20 + (-12)

4x = 8

you can now divide by 4,

x = 2

Can someone help me out

12345 [234]

Answer:

g - 16 is the answer

Step-by-step explanation:

−2 (3g−8g+8) − 9g

Distribute:

= (−2) (3g) + (−2) (−8g) + (−2) (8) + −9g

= −6g + 16g + −16 + − 9g

Combine Like Terms:

=−6g + 16g+ −16+ −9g

= (−6g+16g+−9g) + (−16)

=g+−16

Answer:

=g−16

Find the equation of the axis of symmetry of the following parabola algebraically.

mr Goodwill [35]

Answer:

the equation of the axis of symmetry is $x=8$

Step-by-step explanation:

Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form: $x=constant$ , being that constant the very x-coordinate of the vertex.
