Answer:

= 8n^2 +26n +6

Step-by-step explanation:

(4n+1)(2n+6)

= 8n^2 + 24n +2n +6

= 8n^2 +26n +6

The product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.

To multiply the polynomials (4n+1)(2n+6), you can use the distributive property.

(4n+1)(2n+6) = 4n x 2n + 4n x 6 + 1 x 2n + 1 x 6

Applying the distributive property and simplifying each term:

= 8n² + 24n + 2n + 6

Combining like terms:

= 8n² + 26n + 6

Therefore, the product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.

Step-by-step explanation:

Move all terms that don't contain x to the right side and solve.

Given:

The ratio is:

1.5 kg : 350 g​

To find:

The lowest or simplest form of the given ratio.

Solution:

We know that,

1 kg = 1000 g

We have,

1.5 kg : 350 g​

It can be written as

[tex]1.5\ kg : 350\ g=\dfrac{1.5\ kg}{350\ g}[/tex]

[tex]1.5\ kg : 350\ g=\dfrac{1.5\times 1000\ g}{350\ g}[/tex]

[tex]1.5\ kg : 350\ g=\dfrac{1500\ g}{350\ g}[/tex]

[tex]1.5\ kg : 350\ g=\dfrac{150}{35}[/tex]

[tex]1.5\ kg : 350\ g=\dfrac{30}{7}[/tex]

Therefore, the lowest form of the given ratio is 30:7.

Answer:

2 [tex]\frac{1}{20}[/tex]

Step-by-step explanation:

for question a)

It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)

to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.

E.g.

7 [tex]\frac{1}{4}[/tex] = 7x4 + 1 = 29

Thus, improper fraction would be [tex]\frac{29}{4}[/tex]

do same thing  for other one

thus , [tex]\frac{26}{5}[/tex]

now,

[tex]\frac{29}{4}[/tex] - [tex]\frac{26}{5}[/tex]

however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)

[tex]\frac{145}{20} -\frac{104}{20}[/tex] = [tex]\frac{41}{20}[/tex]

convert back to mixed number

2 [tex]\frac{1}{20}[/tex]

Answer:

Step-by-step explanation:

a) Step1 : write in improper form

Step 2 : Find least common denominator

Step 3: Find equivalent fractions and then subtract

[tex]7\frac{1}{4}-5\frac{1}{5} = \frac{29}{4}-\frac{26}{5}\\[/tex]

            [tex]= \frac{29*5}{4*5}-\frac{26*4}{5*4}\\\\=\frac{145}{20}-\frac{104}{20}\\\\=\frac{145-104}{20}\\\\=\frac{41}{20}\\\\=2\frac{1}{20}[/tex]

b) Keep Change Flip method

[tex]4\frac{1}{4}[/tex] ÷ [tex]2\frac{1}{5} = \frac{17}{4}[/tex] ÷ [tex]\frac{11}{5}[/tex]

            [tex]=\frac{17}{4}*\frac{5}{11}\\\\=\frac{85}{44}\\\\=1\frac{41}{44}[/tex]

Answer: c

Step-by-step explanation:

The required actual length of the train is given as 27 ft.

Given that,
Heather drew the scaled drawing of a train car shown below. She used the scale of 2 cm = 5 ft to complete the drawing.

The scale factor is defined as the ratio of the modified change in length to the original length.

here,
As given,
2 cm = 5 ft
1 cm = 5/2 ft
Tain car length = 10.8 m
Actual length = 10.8 × 5/2 = 27 ft

Thus, the required actual length of the train is given as 27 ft.
