Factorise x² - x with explanation please?​

Mathematics
1 answer:
Assoli18 [71]2 years ago
3 0

Answer:

x(x + 1)

Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)

The probability that an archer hits a target on a given shot is .7 if five shots are fired find the probability that the archer
VikaD [51]
This is a problem in "binomial probability."  Either the archer hits his target or he does not.  This experiment is performed 5 times (so that n=5), and the probability that the archer will hit the target is 0.7 (so that p=0.7).

We need to find the binomial probability that x=3 when the possible outcomes are {0, 1, 2, 3, 4, 5}.

You could use a table of binomial probabilities to evaluate the following:

P(5, 0.7, 3).

Alternatively, you could use a TI-83 or TI-84 calculator and its built-in "binompdf(  " function.

I evaluated binompdf(5,0.7,3) and obtained the result 0.309.

MATH Simplify the expression -6w + (-8) + 1 + (-7w)
Luba_88 [7]

Answer: -13w - 7

Step-by-step explanation:

-6w + (-8) + 1 + (-7w)

Combine the like terms

-8 + 1 = -7

-6w + (-7) + (-7w)

-6w + (-7w) = -13w

-13w + (-7)

However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7

Solve for t. <br> 16 - 2t = t + 9 + 4t<br><br> please help.
Delvig [45]

Answer:t=1

Step-by-step explanation:

16-2t=t+9+4t

Collect like terms

4t+2t+t=16-9

Combine like terms

7t=7

Divide both sides by 7

7t ➗ 7=7 ➗ 7

t=1
