All terms of the expansion are positive.

The true statement is all terms of the expansion are positive.

Binomial expansions are expansions of expressions that have two terms

The expression is given as:

[tex](a - b)^n[/tex]

This means that the expression (a - b) is to be multiplied by itself, n times.

Hence, all terms of the expansion are positive.

The linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

The linear factors of polynomials are the first-degree equations that act as the building block for the simple or complex higher-order polynomials.

Given that, a polynomial 2x⁴+13³+27x²+13x-15, the remainder upon division with x²+4x +5 is zero,

That means, x²+4x +5 is a factor of the given polynomial,

On diving 2x⁴+13³+27x²+13x-15 by x²+4x +5 we get 2x²+5x+3 as quotient that means,  x²+4x +5 and 2x²+5x+3 are the factors of the polynomial,

On factorizing both the factors we get,

(2x+3)(x+1)(x+2+i)(x+2-i)

Hence, the linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

Answer:

let the unit digit be x

and the tens digit be y

so x+y = 9 ---> y = 9-x

the number is 10y+x

the number reversed is 10x + y

3(10y+x) = 8(10x + y)

30y + 3x = 80x + 8y

22y = 77x

2y = 7x

2(9-x) = 7x

18 - 2x = 7x

18=9x

x=2

y=7

the number is 72

check:

number is 72

reverse is 27

is 3(72) = 8(27)

Answer:

The length of Mai's bike ride was 2.1 times the length of Noah's ride.

Step-by-step explanation:

Mai biked 5 1/4 miles today

So he biked, in miles:

[tex]5 + \frac{1}{4} = \frac{5*4 + 1}{4} = \frac{20+1}{4} = \frac{21}{4}[/tex]

Noah biked 2 1/2 miles.

So, in miles, he biked:

[tex]2 + \frac{1}{2} = \frac{2*2 + 1}{2} = \frac{4+1}{2} = \frac{5}{2}[/tex]

How many times the length of Noah’s bike ride was Mai’s bike ride?

We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So

[tex]\frac{\frac{21}{4}}{\frac{5}{2}} = \frac{21}{4} \times {2}{5} = \frac{21*1}{2*5} = \frac{21}{10} = 2.1[/tex]

The length of Mai's bike ride was 2.1 times the length of Noah's ride.

Answer:

The enlarged picture will have a width of 35.8 cm

Step-by-step explanation:

We can solve this question by proportions, using rule of three.

When the length is of 15 centimeters, the width will be of 14.5 centimeters. What is the width when the length is 37 centimeters?

15 cm - 14.5 cm

37 cm - x

Applying cross multiplication

[tex]15x = 14.5*37[/tex]

[tex]x = \frac{14.5*37}{15}[/tex]

[tex]x = 35.8[/tex]

The enlarged picture will have a width of 35.8 cm

Answer:

36.25 cm

Step-by-step explanation:

37.5 divided by 15 is 2.5 then multiply 14.5 by 2.5 and your answer will be 36.25 cm.

0.25 is a decimal and 25/100 or 25% is the percentage for 2/8.

Step-by-step explanation:

The result is: 0.25 and 25% is 2/8 as a decimal and percent.

Here, we have,

given that,

the fraction is:  2/8

now, we have to write as a decimal and percent.

so, we get,

2/8

[ dividing both numerator and denominator by 2 ]

= 1/4

= 0.25

so, we get, 0.25 is a decimal.

now, we have,

0.25 = 25/100 = 25%

so, we have, 25/100 or 25% is the percentage for 2/8.

Answer:

120 kg

the kilograms of beans which can by for $20 are

30*(20/5) = 30.4 = 120 (kg)

Answer: 120 kilograms

Step-by-step explanation:

We can buy 30 kilograms of beans for $5 dollars. We need to find how many kilograms of beans we can buy for $20.

The first step is to divide 20 by 5. Then, using the quotient, we can multiply it by 30 to see how many kilograms of beans we can buy for $20.

20 ÷ 5 = 4.

4 x 30 = 120.

Therefore, we can buy 120 kilograms of beans for $20.
