Answer:
d is the answer brainliest?
Step-by-step explanation:
Answer:
Step-by-step explanation:
It is given that, 
We need to find the value of 
As
Solving LHS
Now comparing the coefficients of 
In LHS the coefficient of is 25
In RHS the coefficient of is
It implies that,
So, the value of is 25.
The answer is D because if you add all the same terms you get the answer
Answer:
r=sqrt45
Step-by-step explanation:
1. 3x+9-9=18-9
3x=9
x=3
2. 4x-12=20
4x-12+12=20+12
4x=32
x=8
3. x+0-0
x=0
4. x/2-2+2=9+2
x/2=11
(2)(x/2)=11(2)
x=22
5. 12x-21=3
12x-21+21=3+21
12x=24
x=2
6. 3x-15=18
3x-15+15=18+15
3x=33
x=11
7. 3x-25=14
3x-25+25=14+25
x=13
8. 3x+16=22
3x+16-16=22-16
x=2
9. 2x-8=2
2x-8+8=2+8
2x=10
x=5
10. 9x-18=9
9x-18+18=9+18
9x=27
x=3
11. x+0=0
x=0
12. 9x-8=19
9x-8+8=19+8
9x=27
x=3
