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 + 2x +3)4x × (x²) = 4x³
4x × (2x) = 8x²
4x × (3) = 12x
Therefore,
4x(x² + 2x +3) = 4x³ + 8x² + 12x

determine whether (7,8) is a solution of 7x+9y=11
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

A triangle has vertices X(2, 1), Y(5, 4), and Z(5, 1). What is the area of the triangle?
Answer:
Step-by-step explanation:
They gave you an easy triangle. You can tell by the coordinates that X and Z are horizontally aligned, and Y and Z are vertically aligned, so Z is a right angle.
Area = 0.5(XZ)(YZ) = 0.5(3)(3) = 4.5 square units.

0.6
Answer:
0.8x or 0.2x
Step-by-step explanation:
20% of x = 20/100 × x = 0.2x
So discount price = x - 0.2x = 0.8x

What is the slope of JK? J=(2, 4), K(6, 1), L(2, -2), M(-2, 1)
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.

Laura has 78 apple trees in her cider farm, with a mean of 460 apples per tree. She has had to get a tree cut down, and after that, the mean of apples per tree became 462 . How many apples were there on the tree that Laura had to cut down?
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.

Find The Value of X in the picture I showed.
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

The coach of a softball team has 8 good hitters and 9 poor hitters. He chooses 5 hitters at random.In how many ways can he choose 4 good hitters and 1 poor hitter?
Answer:
He can choose 4 good hitters and 1 poor hitter in 630 different ways.
Step-by-step explanation:
The order in which the hitters are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In how many ways can he choose 4 good hitters and 1 poor hitter?
4 good hitters from a set of 8.
1 poor hitter from a set of 9. So
[tex]T = C_{8,4}*C_{9,1} = \frac{8!}{4!(8-4)!}*9 = 630[/tex]
He can choose 4 good hitters and 1 poor hitter in 630 different ways.

If x = 5 units, y = 6 units, and h = 6 units, find the area of the trapezoid shown above using decomposition. A. 102 square units B. 30 square units C. 66 square units D. 48 square units
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
