To simplify this, we need to do PEMDAS (parenthesis then exponents, then multiplication and division, then addition and subtraction). Here, we can't combine any like terms in the parenthesis. Since there's no exponents, that means that the next step is to do multiplication. This gives us:
3 - 15y - 21 + 2y - 6
Now we can combine like terms.
(-15y + 2y) + (3 - 21 - 6)
-13y - 24
If the first term of the function is negative then the parabola will open down and it has a maximum value.
If the first term of the function is positive then the parabola will open up and it has a minimum value.
In the case of your example the parabola will open down and will have a maximum value.
hope this helps :)

Answer:
A = 437 mm²
Step-by-step explanation:
The general formula for the area of a triangle:
A = , where 'b' is the measure of the base and 'h' is the measure of the height
Given the dimensions of the triangle in the picture:
A = = 437 mm²
