Answer:
(x+9)(x+9)
Step-by-step explanation:
Factor 81+18x+x^2
x^2+18x+81
=(x+9)(x+9)
Answer:
X=10
Step-by-step explanation:
You can subtract 180 by 110 to get 70. Then you can do 8x+30+70=180
Add 30+70 to get 100
Subtract 100 to 180 to get 80.
8x=80
You divide 8 from both sides which leaves you with x=10.
Answer:
All real numbers are solutions!
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+4=9+5(x−1)
Step 1: Simplify both sides of the equation.
5x+4=9+5(x−1)
5x+4=9+(5)(x)+(5)(−1)(Distribute)
5x+4=9+5x+−5
5x+4=(5x)+(9+−5)(Combine Like Terms)
5x+4=5x+4
5x+4=5x+4
Step 2: Subtract 5x from both sides.
5x+4−5x=5x+4−5x
4=4
Step 3: Subtract 4 from both sides.
4−4=4−4
0=0
1
because 5 plus 4 = 9
and you cant have 9/9
9/9=1
The answer is x=12 after I did the math that is my answer
