Answer:

an = -6 + n

a10 = -6+ 10 =4

Step-by-step explanation:

an should start at one behind the first number so it should be -6. Then we add whatever the sequence is increasing by, which is 1 in this case, multiplied by n.

an = -6 + n

a10 = -6+ 10 =4

Factorise x² - x with explanation please?

Assoli18 [71]

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)

Leviafan [203]

$2700=2200(1+r)^5 \ /:2200\\\\(1+r)^5= \frac{27}{22} \\\\1+r= \sqrt[5]{\frac{27}{22} } \\\\r=\sqrt[5]{\frac{27}{22} } -1$
