Answer:
Answer: x=65
Step-by-step explanation:
Since they're vertical angles both sides are equal to 145 degrees
So, 145-15= 130 to get rid of the constant
Then, 130/2=65
To check you work add up all of your solutions to get 145
2*65=130 & 130+15=145
Therefore, x=65
Answer:
A = 9x² + 12x
Step-by-step explanation:
The area (A) of the rectangle is calculated as
A = height × width
= 3(3x² + 4x) ← distribute parenthesis by 3
= 9x² + 12x
Answer: Both plants grow at same rate ie., 4/3 cm per day
Step-by-step explanation:
8 cm = 6 days
