If the result of [a + M] [a-6] does not contain a linear term, then the number m is equal to a.0 B. - 6 C.6 D. ± 6

If the result of [a + M] [a-6] does not contain a linear term, then the number m is equal to a.0 B. - 6 C.6 D. ± 6

If the result of [a + M] [a-6] does not contain a linear term, then the number m is equal to [C] a.0 B. - 6 C.6 D. ± 6
【A+M】【A-6】=A²-6A+MA-6M=A²+(M-6)A-6M;
∴M-6=0;
M=6;
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

How much is m equal to if M is 3 M2 - 4m + 6 = 0

3 M2 - 4m + 6 = 0
Because Δ = 16-4 * 3 * 6 = - 56 < 0
So the equation has no real roots
If you don't understand, I wish you a happy study!

If 5 / M equals 6 / N, m and N are not zero, then how much is m equal to n,

m/5 = n/6
6m = 5N (multiply both sides by 30)
m/n = 5/6
The answer is 5 to 6

How many jin is a liter of vegetable oil equal to?

Recently, there is a special price for 5 liters of linseed oil in the supermarket, 79 yuan per barrel. I don't know how many jin 5 liters is. The density of edible oil is generally 0.8kg per liter, so 5L is 4kg oil: M = ρ v = 915 * 0

How many jin is a liter of vegetable oil equal to?

One liter is equal to two liters. One liter is 1000 ml. the specific gravity of oil is smaller than that of water. One liter of water is 10 jin. One liter of water is 20 jin. One liter of oil should be less than 20 jin

How much sesame oil is equal to 1 jin of water

About 0.55 liter of linseed oil is equal to the volume of 1 jin of water

How many liters is a kilogram of gasoline equal to

The density of gasoline is about 0.8kg/l, 1kg = 1kg, v = m / ρ = 1 / 0.8 = 1.25l~

How many liters is a kilogram of gasoline equal to

Calculated by density of 0.74
One liter is 0.74 kg
So a kilogram of gasoline is estimated to be between 1.35 and 1.45 liters
The density of 97 gasoline is 0.737 g / ml, that is 0.737 kg / L;
-The density of No. 20 diesel is 0.83 g / ml, that is 0.83 kg / L
So a liter of gasoline is 0.737 kg
One liter of diesel is 0.83 kg

How many liters is a kilogram of diesel oil?

The specific gravity of diesel oil is about 1 liter = 0.86
So the volume of a kilogram of diesel is about 1 / 0.86 = 1.16279 liters

How many liters of diesel is one kilogram of diesel

The density of No.0 diesel oil is generally between 0.84-0.86g/cm 3 at standard temperature (20 ° C)
Therefore, one liter of diesel is only equivalent to 0.84-0.86 kg,
So a kilogram of diesel is 1.16-1.19 liters
