6r+70=-2(35+3r)
multiply the bracket by -2
(-2)(35)=-70
(-2)(3r)=-6r
6r+70=-70-6r
move -70 to the left side
sign changes from -70 to +70
6r+70-70=-70-70-6r
6r=-70-70-6r
move-6r to the left side
6r=-140-6r
move -6r to the other side
6r+6r=-140-6r+6r
12r=-140
divide both sides by 12
12r/12=-140/12
r=-140/12
reduce- by dividing by 4
-140/4=-35
12/4=3
Answer:
r= -35/3 and r=-11 2/3
Answer:
Option 2 which is r^6
Step-by-step explanation:
You need to apply the exponent rules.
Since the r's are the same, you can subtract the exponents.
r^9 - r^3 = r^6
Notice that the bases ("r") stayed the same.
The answer is the option E: E. 8
The explanation is shown below:
1. You have that the triangles shown in the figure attached, are similar, therefore, you can calculate h as following:
(20-4)/h=h/4
16/h=h/h
2. Now, solve for h:
h²=64
h=√64
h=8
Answer:
i think 32
Step-by-step explanation:
128÷12 = 10.6666666666
10.6666666666×3 = 32
