Perfect squares can be divided and multiplied by the same number to get the same number. For example 25/5=5. 5*5=25.
4/2=2, 2*2=4
1/1=1, 1*1=1
9/3=3, 3*3=9
16/4=4, 4*4=16.
Hence the perfect squares.
Its 8 because your not adding your subtracting.
Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30

Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.
Step-by-step explanation:
Volume of cylinder= volume of blood it can hold = 
Given :
Height of cylinder (h) = 9.5 cm
Diameter of cylinder (d) = 0.85 cm
Thus radius of cylinder (r) = 
Putting the values we get:
Volume of cylinder= volume of blood it can hold =
[tex] (1cm=0.1dm)
Thus 0.539 cubic decimeters of blood can be hold by the cylinder.
