Answer:
![6y - 8](https://tex.z-dn.net/?f=6y%20-%208)
Or
![2(3y - 4)](https://tex.z-dn.net/?f=2%283y%20-%204%29)
Step-by-step explanation:
The given expresion is 2y-8+4y.
We want to find an expression that is equal to 2y-8+4y.
We need to group like terms to obtain:
![2y + 4y - 8](https://tex.z-dn.net/?f=2y%20%2B%204y%20-%208)
We can now combine the like terms to get:
![2y + 4y - 8](https://tex.z-dn.net/?f=2y%20%2B%204y%20-%208)
![6y - 8](https://tex.z-dn.net/?f=6y%20-%208)
We can factor 2 to obtain:
![2(3y - 4)](https://tex.z-dn.net/?f=2%283y%20-%204%29)
<span>Using the
formula d=m/v, we first need to convert 5.0 and 45.0 to their SI unit
equivilents. 5.0g is 0.005kg, 45.0cm^3 becomes 0.000045m^3.Therefore, the density of your cube is 0.005/0.000045=111.11 kg/m^3(5 s.f)</span>
Answer: 18
Step-by-step explanation:
Evaluate 7 r − 15 /s
Given that r = 3 and s = 5
7r - 15/s
Substitute 3 for r and 5 for s in the above expression
7(3) - 15/5
= 21 - 3
= 18
The sides
12-3a
12-3a
4(2a-5)=8a-40
so for perimeter we + them
(12-3a)+(12-3a)+(8a-40)
=
2a-16
Answer: Angle CDG, I think.
Step-by-step explanation:
The definition of Corresponding Angle is: On the same side of the transversal. One is interior and the other is exterior.
Since ADE is interior, then the other angle must be exterior.
