Answer:
"Take the square root of both sides of the equation"
A is correct
Step-by-step explanation:
We are given quadratic equation
We need to solve for x. We have to isolate x here.
Here square on x. So, first we get rid of square.
Taking square root both sides to get rid of square.
For example:
a2=25
sqare a2 = +- sqare 25
x2=9/16 to solve for x
sqare x2 +- sqre 9725
x=+- 3/5
Hence, "Take the square root of both sides of the equation"
Answer: x = 4
Step-by-step explanation:
2(x+1)=10
Distributive properties
a*(b+c)=(a*b)+(a*c)
Using distributive properties
Then
2*(x+1)=(2*x)+(2*1)
2*(x+1)=2x+2
Now, commutative properties
a*b=b*a
Addition is cumulative
a+(-b)=(-b)+a
Therefore applying to 2x+2
2x+2+(-2)=2x+(-2)+2
Then, applying to the equation
2x+2+(-2)=10+(-2), +×-=-
2x+2 -2=10-2
2x=8
Using division properties
ax=b
If a is none zero
Then ax/a=b/a
Therefore x=b/a
Applying that to 2x=8
2x=8. Divide both side by 2 which is none zero
2x/2= 8/2
x=4
Option B
Subtraction Property of equality

Answer:
Lets break it you add -45 to 10 and get -35 then you add -20 to 20 making 0 so the answer is -35
Step-by-step explanation:
Answer:
x=10
Step-by-step explanation:
1/2x+4=9
subtract 4 from both sides
1/2x=5
multiply both sides by 2 to get x by itself
x=10
Answer:
a = 5
Step-by-step explanation:
