Answer:

x=4

Step-by-step explanation:

9=1/4 (6x+12)

Multiply each side by 4

4*9 =4*1/4 (6x+12)

36 = (6x+12)

Subtract 12 from each side

36-12 = 6x+12-12

24 = 6x

Divide each side by 6

24/6 = 6x/6

4 =x

4w2 + 3W

timama [110]

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

$Length = 4w^2 + 3w - 1$

$Width = 5w - 2.$

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

$Area = 20w^3 + 7w^2 - 11w + 2$

Step-by-step explanation:

Given

$Length = 4w^2 + 3w - 1$

$Width = 5w - 2.$

Required

Determine an expression for the area

Area is calculated as:

$Area = Length *Width$

$Area = (4w^2 + 3w - 1) * (5w - 2)$

Expand

$Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2$

Collect like terms

$Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2$

$Area = 20w^3 + 7w^2 - 11w + 2$

Answer this question thanks:)

First multiply 2 to both sides to isolate q. Since 2 is being divided by q, multiplication (the opposite of division) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

$\frac{q}{2}$ × 2 < 2 × 2

q < 4

For the graph will you have a empty or colored in circle?

If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.

If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.

Which direction will the ray go?

If the variable is LESS then the number then the arrow will go to the left of the circle.

If the variable is MORE then the number then the arrow will go to the right of the circle.

In this case your inequality is:

q < 4

aka q is less then four

This means that the graph will have an empty circle and the arrow will go to the left of 4. (look at image below)

Hope this helped!

Dilate a triangle with vertices (0,0), (0,2) and (2,0) using the scale factor k=3. What is the value of the ratio (new to origin

seropon [69]

Answer:

Part a) The ratio of the perimeters is $3$

Part b) The ratio of the areas is $9$

Step-by-step explanation:

Part A) What is the value of the ratio (new to original) of the perimeters?

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z-----> the scale factor

x-----> the perimeter of the new triangle

y-----> the perimeter of the original triangle

$z=\frac{x}{y}$

we have

$z=3$

substitute

$\frac{x}{y}=3$

Part B) What is the value of the ratio (new to original) of the areas?

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> the area of the new triangle

y-----> the area of the original triangle

$z^{2}=\frac{x}{y}$

we have

$z=3$

substitute

$\frac{x}{y}=3^{2}$

$\frac{x}{y}=9}$
