<span>He could represent a rectangle with dimensions of x – 1 and x – 6, then demonstrate that the area equals the sum of x², –x, –6x, and 6.</span>

Answer:

Step-by-step explanation:

Brent can use a rectangle to illustrate the area represented by (x² - 7x + 6).

Next, we will factor this polynomial:

x² - 7x + 6 = x² - 6x - x + 6

                = x(x - 6) - 1(x - 6)

                = (x - 1)(x - 6)

This means that (x - 1) and (x - 6) will represent the dimensions of a rectangle, allowing for the multiplication of the sides to represent the area of the rectangle.

Gus has a fish tank that holds 471047104710 inches^3 3 cubed of water. He is using a cylinder shaped bucket with a radius of 555
tester [12383]

Answer:

Gus must fill the cylindrical bucket three times to get it filled for the tank

Step-by-step explanation:

Extracting essential details from the query:-

*** A fish tank has a volume of 4710 inches^3

*** The tank owner utilizes a cylindrical bucket for filling the tank

*** The bucket has a radius of 5 inches and a height of 20 inches

*** We need to compute how many times Gus has to fill the bucket to fully fill the fish tank.

Since the container used for filling the tank is cylindrical, we will apply the formula for finding a cylinder's volume to derive the bucket's volume used for filling the tank.

Volume of a cylinder = π × r^2 × h. The radius of the cylindrical bucket is stated as 5 inches while the height is mentioned as 20 inches.

The bucket's volume is therefore calculated as 3.14 × 5^2 × 20 = 1570 inches^3

Next, it is given that the fish tank’s capacity is 4710 inches^3. To find out how many times the bucket can fill the tank, we must divide the tank's volume by the bucket's volume:

4710/1570 = 3 full buckets.

Thus, Gus has to fill the bucket three times for filling the fish tank completely without spillage.

Joaquin is four more than half Marjorie’s age. Marjorie is also 32 less than three times Joaquin’s age.
babunello [11817]

Answer:

Her age is 40 years

Step-by-step explanation:

Let Jerry's age be represented as j

Let Marjorie's age be denoted as m

The first part of the question states:

j = 4 + m/2

For the second equation:

m = 3j - 32

Multiply the first equation by 2 to get:

2j = 8 + m

Leading to m = 2j - 8

Set both equations for m equal to each other:

2j - 8 = 3j - 32

By simplifying, we get:

3j - 2j = 32 - 8

Therefore, j = 24

Now substituting back:

m = 2j - 8

m = 2(24) - 8

Thus, m = 48 - 8

Final result: m = 40

Complete the sentence below. If (3x2 + 22x + 7) ÷(x + 7) = 3x + 1, then (x + 7)(???????) =???? .
Zina [12379]

Response: The outcome is (x+7)(3x+1)=33x^2+22x+7.

Detailed explanation: Suppose that

(3x2 + 22x + 7) \div(x + 7) = 3x + 1,

we need to finalize the subsequent sentence:

(x+7)(???)=???

We have the polynomial division algorithm as follows

\textup{If }a(x)\times b(x)=c(x),\\\textup{then, we have }\\\\\dfrac{c(x)}{b(x)}=a(x)~~~~~\textup{or}~~~~~~c(x)\div b(x)=a(x).

In this equation, a(x) denotes the quotient, b(x) indicates the divisor, and c(x) stands for the dividend.

Using this principle in the current problem, it results in

\textup{since }(3x2 + 22x + 7) \div(x + 7) = 3x + 1,\\\\\textup{so, }\\\\(x+7)(3x+1)=3x^2+22x+7=0.

Consequently, the full sentence would be

(x+7)(3x+1)=3x^2+22x+7=0.
