I took this class last year... how could I have forgotten all of this???
Answer:
D ≈ 0.925926 g/cm³
Step-by-step explanation:
Density = Mass / Volume
Step 1: Define
M = 25 g
V = (3 cm)³ = 27 cm³
D = ?
Step 2: Substitute and Evaluate for Density
D = 25g / 27 cm³
D = 25/27 g/cm³
D ≈ 0.925926 g/cm³
Answer:
8 were absent

20% of 40 is 8
Answer:
Hope this helps!!
Step-by-step explanation:
2ya and 2yb where a and b have no common factors and a and b are polynomaals
a=(x+2)(x+3)
b=(x+4)(x+5)
no common factors betwen a and b
so
2ya=2y(x+2)(x+3)=2yx²+10xy+12y
2yb=2y(x+4)(x+5)=2yx²+18xy+40y
the 2 polynomials are 2yx²+18xy+40y and 2yx²+10xy+12y
To solve for the solution of this system of linear equation, it is best to use substitution. From the first equation, x = 3y
Substituting the expression on the right for the value of x on the second equation,
-2(3y) + 3y = 16
Solving for the value of y gives y = -5 1/3
With this value of y, solving for x gives x = -16
Thus, the solution for this system of linear equation is (-16, -5 1/3)
