**Answer:**

61

**Step-by-step explanation:**

1. let the unknown be x

2. using theorem of Pythagoras that states the hypotenuse will be equal to the sum of the other two sides we can determine that 75=14+X

3. this implies that X=75-14

4. therefore X= 61

**Answer:**

m<b = 71

m<d = 71

**Step-by-step explanation:**

Vertical angles = congruence

2x+1=x+36

subtract x

x+1=36

subtract 1

x = 35

PLUG IN

m<b = 2x + 1

2(35) +1

70+1

71

m<d = x+36

35+36

71

First, you need to see which number all of these numbers have in common, and that is number 4. So, let's start:

-4(x2 - 4x + 6)

The expression in the brackets cannot be factored further, which means that the answer above is the complete factor of the original expression. Hope it helps. :)

**Answer:**

2x^2 + 8xy - 2y^2

**Step-by-step explanation:**

2X(X+y) + 2y(3X-y)

2x^2 + 2xy + 6yx - 2y^2

2x^2 + 8xy - 2y^2
