Step-by-step explanation:
Answer:
2(5)+5=15
Step-by-step explanation:
1. you have the equation 2b+c
2. then you add the numbers for c and b
3. so b=5 and c=5
4. once you add it into the problem then you get 2(5)+5 make sure you remember to times 2 x 5
5. then you do PEMDAS
6. you do multiply so 2x5 is 10
7. then do 10+5 and you get 15 as your answer.
First bring the 9 to the other side by subtracting it so you get the equation; x^2+10x-9=0 and you answer would be x=9 and x=1. you may have wrote the question own wrong? is the x^2 negative? if so i give my answer :)
