3 over the whole value of (x2−5x+6) = a over the whole value of (x−2) + b over the whole value of (x−3)
muminat
I guess that's all you can do
to find a and b you need more information

b=-a -> a (x-3)-a (x-2)=3
a [x-3-(x-2)]=3
a (x-3-x+2)=3
a*(-1)=3
a=3:(-1)
a=-3
b=-a=-(-3)=3

Wayne has 303 marbles if he gives away 123 of the marbles equally to 3 friends about how many marbles will wayne give each frien
Lera25 [3.4K]

Answer:

Each friend receives 41 marbles, Wayne has 180 marbles left.  

Step-by-step explanation:

Wayne starts with 303 marbles total.  If he decides to give 123 of his marbles away to his friends, we can subtract this amount from his total to get how many he has left:

303 - 123 = 180 marbles left

We also want to know how many marbles each of his three friends receives.  Since he wants to split them equally, we need to divide the number he is giving away by 3:

123 ÷ 3 = 41 marbles a piece to each friend

Find the area of the Shaded region use ,3.14. note that the top of the figure is a semicircle
Tema [17]
The area is 20.5632 cm sq.

Lets break it down:

Triangle- the area of a triangle is bh/2 (base×height÷2). If we plug in the numbers, the base is 4.8 and the height is 4.8. 4.8×4.8= 23.04÷2= 11.52

Semi circle- the area of the semi circle is pi×radius×radius. We have the diameter (4.8) so we would need to divide 4.8 by 2 to get 2.4. 2.4×2.4×3.14= 18.0864. We need to divide that by 2 because its a semi circle so 18.0864÷2= 9.0432

11.52+9.0432= 20.5632 cm sq.

hope this helps!
