To do that, use the Pythagorean's Theorem:
a²+b²=c²
in this case, c = 3, and b = 1.
a² + 1² = 3²
a² + 1 = 9
a² = 8
a = √8
Now to find z, use the Pythagorean's Theorem again:
a² + b² = c²
where √8 = a and 8 = b, and z = c.
√8² + 8² = z²
8 + 64 = z²
72 = z²
z = √72
To simplify this, take out the largest perfect square, or 36:
z = √36√2
z = 6√2
So your answer would be B.

their present age-
Answers
Answer:
4 and 9
Step-by-step explanation:
let their ages be x and x - 5, then in 4 years their ages will be
x + 4 and x - 5 + 4 = x - 1 , and the product is 104, thus
(x + 4)(x - 1) = 104 ← expand factors on left using FOIL
x² + 3x - 4 = 104 ( subtract 104 from both sides )
x² + 3x - 108 = 0 ← in standard form
(x + 12)(x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 12 = 0 ⇒ x = - 12
x - 9 = 0 ⇒ x = 9
However, x > 0 ⇒ x = 9
Thus
Their present ages are 9 and 9 - 5 = 4

What issimplification?
In mathematics, reducing an expression, fraction, or problem to a simpler form is referred to as simplification. With calculations and solution, the problem is made simple. Make something simpler by simplifying it.
We are given a polynomial as
5x - 5 + + 4x -
+ 8
Now, in order to simplify the given polynomial, we will combine the like terms of the polynomial.
On combining the like terms, we get
+ 9x + 3
Hence, the polynomial after simplification is obtained as + 9x + 3.

Answer:
1000/t=w
Step-by-step explanation:
The first thing we need to do is, multiply 1000 to both sides,
c(1000)=wtc
now we need to divide both sides by tc
c(1000))/(tc)=w
The c's on the left side will cancel out
1000/t=w
