Answer:

$y =112$

Step-by-step explanation:

Given

The attached triangle

Required

Find y

The attached triangle is isosceles; so:

$x - 5=34$

Also, we have:

$y + x - 5 + 34=180$ --- angles in a triangle

Substitute: $x - 5=34$

$y + 34 + 34=180$

Collect like terms

$y =- 34 - 34+180$

$y =112$

Answer:

$(10x-1)^2$

Step-by-step explanation:

Here we are going to apply the rule of "Square of the difference". The rule is as given below

$(a-b)^2=a^2-2 \times a \times b + b^2$ ---------(A)

Now we have our original polynomial as

$100x^2-20x+1$

Which can be re written as

$(10x)^2-2 \times 10x \times 1 + 1^2$ ---------------(B)

Hence comparing it with (A)

$a=10x$

$b=1$

Applying the rule on (B)

$(10x)^{2}-2 \times 10x \times 1 + 1^2 = (10x-1)^2$

Hence our answer is

$(10x-1)^2$
