Hello,
It must be well know that
x²-(a+b)x+a*b=0 is a equation of 2nd degree with a and b like root.
===>a+b=1
and a*b=-90
N'en déplaise Excellency. (think before delete!)
In order to find the area for a strange shape, you divide it up into simpler figures. In this case, you already know that it can be divided into 4 triangles, so find the area of each triangle and add them up. Hope this helped!
You need to find the Least common Multiple which would be the 36 customer. because 9 times 4 is 36 and 12 times 3 is 36. 36 is the least common multiple
Answer:
Step-by-step explanation:
5/6
Answer:
5 and 61
Step-by-step explanation:
Using Pythagoras' identity in the right triangles
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
(1)
c² = a² + b² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )
c = = 5
(2)
c² = a² + b² = 11² + 60² = 121 + 3600 = 3721 ( take the square root of both sides)
c = = 61
