How to factor 5m2-29m+20?

ser-zykov [4K]

Question :

5m^2 - 29m + 20

Steps:

What can u factor to get 20?

you can make 5 and 4 to make 20 so,..

1. Break it into groups

(5m^2 - 4m) + (-25m + 20)

*Factor out m from (5m^2 - 4m) : m(5m - 4)

*Factor out -5 from (-25m + 20) : -5(5m - 4)

2. Then, you can factor out the common term : (5m - 4) because they both have it. And then u would move the m by the -5 so,...

= (5m - 4)(m - 5) <======= <em>Answer</em>

Hope this helped!!!

One cubic meter of water weighs approximately 2200 pounds. There are 100 cm in one meter. If you have a box-shaped fish tank tha

Diano4ka-milaya [45]

Answer:

158.4 pounds

Step-by-step explanation:

first find the volume of the tank

$V = 30 \times 30 \times 80$

$V = 72000 cm^3$

to convert this to m^3 we know that 1m = 100cm

$V = 72000 cm^3 \times \left(\dfrac{1\,\text{m}}{100\,\text{cm}}\right)^3$

$V = 72000 cm^3 \times \left(\dfrac{1\,\text{m}^3}{100^3\,\text{cm}^3}\right)$

the cm^3 cancel out.

$V = \dfrac{72000}{100^3} m^3$

$V = 0.072\,m^3$

by simply converting the side-lengths to meters beforehand can give you this answer directly:

$V = 0.3 \times 0.3 \times 0.8 = 0.072 m^3$

it is given that 1 meter cube of water weighs about 2200 pounds.

$1\,m^3 = 2200 \,\text{lb}$

multiply both sides with 0.072 to find our answer:

$1\,m^3 \times 0.072 = 2200 \times 0.072 \,\text{lb}$

$0.072\,m^3 = 158.4 \,\text{lb}$

hence the weight of the water in the tank would be 158.4 pounds!
