1. -3(n + 1) = 3. 
-3n + -3 = 3. 
-3n + -3 + 3 = 3 + 3. 
-3n = 6. 
-3n/-3 = 6/-3. 
n = -2. 

2. 2(c - 12) = 0. 
2c - 24 = 0. 
2c - 24 + 24 = 0 + 24. 
2c = 24. 
2c/2 = 24/2. 
c = 12. 

3. 38 = -6t - 4. 
38 + 4 = -6t - 4 + 4. 
42 = -6t. 
42/-6 = -6t/-6. 
-7 = t.

Which equation has the same solutions as the equation given below?
Lapatulllka [165]

Answer:

B

Step-by-step explanation:

Also solved eveything

(x+9)^2=49

x^2+18x+81=49

x^2+18x+32=0

a=1, b=18 and c=32

x= (-18 +/- Sqrt (18^2-4×32))/2

x= (-18 +/- Sqrt (324-128))/2

x= (-18 +/- Sqrt (196))/2

x= (-18 +/- 14)/2

x= (-18 +14)/2 = -4/2 =-2

OR

x= (-18 -14)/2 = -32/2 =-16

Help<br> Simplify. 2−4÷2+2^3
Radda [10]
Hey there!

If we use pemdas:

P - Parentheses
E - Exponents
M - Multiplicatiom
D - Division
A - Addition
S - Subtractiom

We know we have to evaluate the exponent first. Two to the rid power is equal to 8. Therefore, we have:

2 - 4/2 + 8

Next, we do the division. -4/2 = -2, so we have:

2-2 + 8 = 0 + 8 = 8

Hope this helps!
