Compare factoring by grouping to factoring out the greatest common factor.

Mathematics
1 answer:
Blababa [14]3 years ago

Answer:

(3x + 10)(2x + 1)

Step-by-step explanation:

Factor by grouping: 6x2 + 3x + 20x + 10.

This is a polynomial written with four terms that don't have a single common factor among them. However, the first two terms have a common factor (3x), and the last two terms have a common factor (10). This situation doesn't answer all of our wildest factoring dreams, but we'll take it.

By pulling out the common factors for each pair of terms, we can rewrite the original polynomial like this:

3x(2x + 1) + 10(2x + 1)

These two terms now have a common factor of (2x + 1). Seems like we should be able to do something with that information, don't you think? In fact, we can pull out this common factor and rewrite the polynomial again:(3x + 10)(2x + 1)

Calculate to the nearest million m³.the current amount of water in the berg river dam​
swat32

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the dimension of the dam is not given.

However, a general way of calculating volume is to calculate the base area and the multiply by height.

Take for instance,the dam has a rectangular base of 20m by 30m.

The base area will be

Area = 20m * 30m = 600m²

If the height of the water in the dam is 40m, then the volume is:

Volume = 600m² * 40m

Volume = 24000m³

Factor the trinomial 6y squared + 19y + 15
Musya8 [376]

Answer:

1.y = -5/3 = -1.667

2. y = -3/2 = -1.500

Step-by-step explanation:

90    +    -1    =    -91  

     -45    +    -2    =    -47  

     -30    +    -3    =    -33  

     -18    +    -5    =    -23  

     -15    +    -6    =    -21  

     -10    +    -9    =    -19  

     -9    +    -10    =    -19  

     -6    +    -15    =    -21  

     -5    +    -18    =    -23  

     -3    +    -30    =    -33  

     -2    +    -45    =    -47  

     -1    +    -90    =    -91  

     1    +    90    =    91  

     2    +    45    =    47  

     3    +    30    =    33  

     5    +    18    =    23  

     6    +    15    =    21  

     9    +    10    =    19

Sorin hits a cricket ball straight up into the air. After 1.5s, the ball is falling straight down with a speed of 6.5 m/s. We wa
sveticcg [70]

Step-by-step explanation:

We have, Sorin hits a cricket ball straight up into the air. After 1.5 s, the ball is falling straight down with a speed of 6.5 m/s.

We want to find the initial vertical velocity of the ball.

The relation between initial speed, final speed, acceleration and time is given by using first equation of kinematics. Let v₀ is the initial speed. So,

v=v_o +at

Here, v = -6.5 m/s, t = 1.5 s and a = -g

v_o=v-at\\\\v_o=v+gt\\\\v_o=-6.5+9.8\times 1.5\\\\v_o=8.2\ m/s

So, the initial velocity of the ball is 8.2 m/s and the formula used is (1).
