Answer:

16x^3 + 8x^2 + 12x

Step-by-step explanation:

Given the product 4x(x^2+2x+3)

On Expanding

4x(x^2+2x+3)

= 4x(x^2)+4x(2x)+4x(3)

=  16x^3 + 8x^2 + 12x

Hence the Area of the model is 16x^3 + 8x^2 + 12x

The area model is as follows:

4x × (x²) = 4x³

4x × (2x) = 8x²

4x × (3) = 12x

The area model that will be use to multiply 4x(x² + 2x +3) is as follows:

4x × (x²) = 4x³

4x × (2x) = 8x²

4x × (3) = 12x

Therefore,

4x(x² + 2x +3)  = 4x³ + 8x² + 12x

Answer:

x = 4

Step-by-step explanation:

You can do this by realizing that since JG is the diameter then 6 + 11x + 22x - 1 must equal 180 minus 43 because that is the measure of HG. So then just set it up like an algebra equation.

137 = 6 + 11x + 22x - 1

137 = 33x + 5

132 = 33x

x = 4

Answer:

C. 66 square units

Step-by-step explanation:

The area of the middle rectangle would by base × height, or y × h, or 6 × 6.

The area is 36.

The area for one triangle would 1/2 × base × height.

(But since there are two triangles to solve for, the 1/2 is not necessary, and we can just do base × height again.)

So, it would be x × h, or 5 × 6.

The area is 30.

Combine both areas to get the whole area of 66 units²

Answer:

-3/4

Step-by-step explanation:

First, we find the change in x & change in y.

Change in x: 6 - 2 = 4

Change in y: 1 - 4 = -3

Since slope is rise (change in y) over run (change in x),

-3/4 is the slope.

Answer:

(7, 8) is NOT a solution to the equation

Step-by-step explanation:

x = 7 and y = 8 so fill those into the equation

7(7) + 9(8) = 11

49 + 72 = 11

121 = 11

this makes the equation NOT true

So no, (7, 8) is NOT a solution to the equation

Answer:

The tree that Laura had to cut had 306 apples.

Step-by-step explanation:

Given that Laura has 78 apple trees in her cider farm, with a mean of 460 apples per tree, but then she has had to get a tree cut down, and after that, the mean of apples per tree became 462, to determine how many apples were there on the tree that Laura had to cut down, the following calculation must be performed:

(78 x 460) - (77 x 462) = X

35.880 - 35.574 = X

306 = X

Thus, the tree that Laura had to cut had 306 apples.

Option A and Option D represents the equation of area of rectangular piece which are A=4×[tex]2\frac{1}{2}[/tex] and A=4×5/2.

The area of Rectangle is length times of width.

Given that A rectangular piece of glass is shown.

The length is measured as 4 feet.

The width is measured as 2 and one-half feet.

We have to find the  equations can be used to find the area of the piece of glass.

Area=Length×width

Area=4 feet × 2 and one-half feet

=4×[tex]2\frac{1}{2}[/tex]

=4×5/2

Hence, Option A and Option D represents the equation of area of rectangular piece which are A=4×[tex]2\frac{1}{2}[/tex] and A=4×5/2.
