The product of the polynomial is x² - x + xy + 16y - 2y² - 30

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Polynomials are classified based on degree as linear, quadratic, cubic and so on.

Given the polynomial:

(x + 2y - 6)(x - y + 5) = x² + 2xy - 6x - xy - 2y² + 6y + 5x + 10y - 30

= x² - x + xy + 16y - 2y² - 30  

The product of the polynomial is x² - x + xy + 16y - 2y² - 30

Answer :

According to the Question

Diameter of a circle field is 40m and that of another 96m .

We have to find the diameter of the circle whose area is equal to the sum of the area of given two circular fields.

Radius of field whose diameter is 40 m

→ r = 40/2 = 20m

Radius of field whose diameter is 96 m

→ r' = 96/2 = 48m

Now, calculating the diameter of Larger circular field.

Let the radius of larger field be R m .

Now, according to the given statement

Sum of Area of given two circular fields = Area of larger field

➠ πr² + πr'² = πR²

➠ π ( r² + r'²) = π R²

➠ 20² + 48² = R²

➠ 400 + 2304 = R²

➠ 2704 = R²

➠ √2704 = R

➠ 52 = R

Therefore, Diameter = 2 × R = 2×52 = 104 m

So, the diameter of Larger circular field is 104 m .

Answer:

Area of circular field(2)=[tex]πr^2[/tex]

=[tex]π×(20)^2[/tex]

=[tex]400π[/tex]

Area of circular field(2)=[tex]πr^2[/tex]

=[tex]π×(48)^2[/tex]

=[tex]2304π[/tex]

Let the radius of circular field that is formed so be r meter(m).

Now,

[tex] \cancel\pi {r}^{2} = 2704 \cancel\pi[/tex]

[tex] {r}^{2} = 2704[/tex]

[tex]r = \sqrt{2704} [/tex]

[tex]r = 52 \: m[/tex]

Diameter=[tex]2r[/tex]

Diameter=[tex]2×52[/tex]

Diameter=[tex]104 m[/tex]

Direct proportion: If a variable increases then other variable also increases with a constant factor  i.e.  y = kx

Inverse proportion:  if a variable increases then other variable decreases with a  constant factor  i.e   xy = k

Assume that food will last for d days if 20 more persons join the camp.

Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,

Days x number of persons = constant

Equate the product of 300 persons and 42 days  with (300 + 20) person and d days to solve for d.

[tex](300+20) *d=300*42[/tex]

⇒ [tex]d = \frac{12600}{320}[/tex]

⇒ [tex]d =\frac{1260}{32}[/tex]

⇒ [tex]d=\frac{315}{8}[/tex]

⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]

Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction

17 is what percent of 68?

Its 25%

17/68*100

= (17*100)/68

= 1700/68 = 25

Answer:

25%

Step-by-step explanation:

Question : 17 is what percent of 68?​

Answer :

To solve this let the unknown percentage be x .

Let us solve now.

68 × x% = 17

68 × [tex]\frac{x}{100}[/tex] = 17

And now let us find the percentage by making x as the subject.

[tex]x=\frac{17*100}{68}[/tex]

[tex]x = \frac{1700}{68}[/tex]

[tex]x =25[/tex]

Therefore, the percentage is 25%

Answer:

When x=0 the friend is 200 miles from the restaurant and at x=5 the friend reaches the restaurant. When x=0 you are 100 miles from the restaurant, so 100 is the y intercept, and when x=5 you reach the restaurant so 5 is the x intercept. We have y=mx+100 and y=0 when x=5, so 0=5m+100 therefore m=-20 and the equation is y=-20x+100.

Answer:

42. A

43. C

Step-by-step explanation:

42. The answer is A. This is because we are distributing (multiplying) the 7.2 to each number in the parentheses.

43. If Hal ran 4.5 laps, then he ran...

0.65 mil (since each lap is 0.65 miles)* 4.5 (laps) = C. 2.925 miles.

Answer:

42. A, distributive property  tells us how to solve expressions in the form of a(b + c).

43. 0.65 miles x 4.5 laps = 2.925, C
