sergiy2304 [10]

Answer:

x = 93

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

x - 73 + x + 67 = 180

2x - 6 = 180 ( add 6 to both sides )

2x = 186 ( divide both sides by 2 )

x = 93

There are 9 pieces in total, there are 3 options for the first piece (3 piano pieces), and the remaining 8 pieces can be permuted. The number of possible arrangements is:

$n=3*\frac{8!}{(8-8)!}\\ n=3*8*7*6*5*4*3*2*1\\n=120,960\ ways$

Find the product of (x − 5)2

Igoryamba

Answer: The product is $x^2-10x+25$

Step-by-step explanation:

Since we have given that

$(x-5)^2$

We need to find the product:

Since we know that

$(a-b)^2=a^2-2ab+b^2$

Here, a = x

and

b = 5

So, it becomes,

$(x-5)^2=x^2-2\times x\times 5+5^2=x^2-10x+25$

Hence, the product is $x^2-10x+25$
