Answer:
<h3>
A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78</h3>
Step-by-step explanation:
H = 2x+6 - the hight
3H = 3(2x+6) - triple the hight
3H-5 = 3(2x+6) - 5 - five less than triple the height
Area of triangle: A = 0.5BH
B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13
H = 2x+6
So:
A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78
A = 6x² + 49x + 78
Answer:
y=10x
Step-by-step explanation:
First find the domain(the set of all first coordinates in a function) by finding where the equation(a mathematical statement that says two expressions have the same value; any number sentence with an = sign) is defined.
After that you should know what to do. I don't know how to work this problem cuz i'm barely in 9 grade. But somehow, I know this.
(−∞,∞)
{x|x∈R}
If this helped, please let me know and give me brainliest, please!!
If this is incorrect, please let me know so I can fix it!
Answer:
let me make it its equation I have done this but if this will work have a good day
