Answer:

x^3 -x^2 -17x +12

Step-by-step explanation:

Use the distributive property and collect terms.

(x +4)(x^2 -5x +3) = x(x^2 -5x +3) +4(x^2 -5x +3)

= x^3 -5x^2 +3x +4x^2 -20x +12

= x^3 -x^2 -17x +12

1. Find the HCF of the following numbers by prime factorisation and continued division method10,35,40

statuscvo [17]

Answer:

Step-by-step explanation:

10 = 2*5

35 = 5*7

40 = 2*2*2*5

The number 5 is common to all three factorisations

So the HCF = 5.

Continued division:

10 and 35:

10) 35(3

5)10(2

- so the HCF of 10 and 35 is 5.

10 and 40:

10)40( 4

So the HCF of 10 and 40 is 10

We found HCF of 10 and 35 is 5 so:

HCF of 10, 35 and 40 is HCF of 5 and 10 which is 5.

The population of the town is 2500 and is decreasing at a rate of 3% per year. determine the population after 11 years

Debora [2.8K]

Answer:

$\huge \boxed{ \boxed{1675}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

percent
percentage words problem
PEMDAS

<h3>given:</h3>

population:2500
decreasing rate:3%

the population after 11 years

<h3>let's solve:</h3>

according to the question

population decreases in 1 year

$2500 \times 3\% \\ 2500 \times \frac{3}{100} \\ 25 \times 3 \\ 75$

population will decrease in 11 years

75×11
825

so the population of the town after 11 years will be

2500-825

Find the measures of the angles formed by (a) two consecutive radii and (b) a radius and a side of the given regular polygon.14.

Bezzdna [24]

Answer:

Step-by-step explanation:

Let radius = r and side of a regular polygon = s

a) The consecutive radii = r + r + 1

i) For Square ( 4- sides) : r + r + 1 = 90°

2r + 1 = 90°

ii) For Pentagon (5- sides) : 2r + 1 =108°

iii) For Hexagon (6- sides): 2r + 1 = 120°

iv) For Heptagon (7- sides): 2r + 1 = 129°

v) For Octagon (8- sides): 2r + 1 = 135°

vi) For Nonagon (9- sides): 2r + 1 = 140°

vii) For 20 sides: 2r + 1 = 162°

b) A radius and a side = r + s

i) For Square (4- sides): r + s = 90°

ii ) For Pentagon (5- sides): r + s = 108°

iii) For Hexagon (6- sides): r + s = 120°

iv) For Heptagon (7- sides): r + s = 129°

v) For Octagon (8- sides): r + s = 135°

vi) For Nonagon (9- sides): r + s = 140°

vii) For 20 sides: r + s = 162°
