Answer:
-3x+2
Step-by-step explanation:
Since it's addition you just combine all like terms so,
5x+4
-8x-2
= -3x+2
A polyhedron is a 3D solid with many faces
Answer:
RC1. 5
RC2. 8
RC3. a
RC4. 3
Step-by-step explanation:
So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.
so,
8 = 8
C = 10
A = 6
---------------------------------------------------------------------
the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.
( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)
RC1. a/3 = C/_
substitute
6/3 = 10/_
3 * 10 = 30
6 * _ =30
30/6 = 5.
Rc2. 4c = 5_
4*10 = 5*_
40/5 = 8
RC3. 3c = 5*_
3*10 = 5*_
30/5 = 6
RC4. 4a = 8*_
4 * 6 = 8*_
24/8 = 3
good luck with your schoolwork/homework!

Answer:
Step-by-step explanation:
Initial number of sick wolves = W(0) = 10
At time t, no. of sick wolves = W(t)
Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:
Mathematical model of above case is:
Answer:
