Answer:

1) (3c + 1 )(3c + 2)

2) 8x^2 + 26x  - 7

3) 6

4) 16x^2 - 48xy^3 + 36y^6

5) (5x - 2y)(2x - 5y)


Step-by-step explanation:

1) 9c^2 + 9c + 2 = (3c + 1 )(3c + 2)

2) (4x - 1)(2x + 7)

= 8x^2 + 28x - 2x - 7

= 8x^2 + 26x  - 7

3) 7m^6n^5

Highest degree is 6 (m^6)

answer: 6

4)

(4x - 6y^3)^2

= (4x)^2 - 2(4x)(6y^3) + (6y^3)^2

= 16x^2 - 48xy^3 + 36y^6

5)

10x^2 - 29xy + 10y^2

= (5x - 2y)(2x - 5y)

because if if distribute (5x - 2y)(2x - 5y)

= 10x^2 - 25xy - 4xy + 10y^2

= 10x^2 - 29xy + 10y^2

Answer:

Step-by-step explanation:

1)

A. 2 meters to centimeters

1 m = 100 cm

2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2

B)108 centimeters to meters

100 cm =1 m

1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m

C)2.49 meters to centimeters

1 m = 100 cm

2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm

D)50 centimeters to meters

100 cm = 1m

1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m

E)6.3 meters to centimeters

1 m = 100 cm

6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630  cm

F)7 centimeters to meters

100 cm = 1 m

1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m

2)

a)4 meters to millimeters

1 m = 1000 mm

4 m = 4000 = 4 \times 10^3 mm

b)1.7 meters to millimeters

1 m = 1000 mm

1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm
