The house wall, the ground and the ladder form a right triangle, where the ladder is the hypotenuse.
Ladder = sqrt (25^2+10^2) =5sqrt(29)
Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
Answer:
A'= (0,4)
B'= (-1,2)
C'= (2,1)
D'= (2,3)

Let y = 0 to find the zeros.

We can now split the middle term into factors of 6 that add up to 5.

Group the first two terms, and group the last two terms, and factorise.


Group like terms.

Now, we know that in order for a zero to occur, either x + 3 = 0 or x + 2 = 0.
Hence, x = -3 and -2 are the zeros in this quadratic.
Answer:
11^2 + b^2 = 16^2
121 + b^2 = 256
b^2 = 135
b = 3 X q(15)
