I believe it is standard. The equation for standard is ax+by+c.
Answer:
for 2. I don't think it can be a triangle
Answer:
3320in²
Step-by-step explanation:
heron formula = √s(s-a)(s-b)(s-c)
when s = (a+b+c)/2
s = (16+35+25)/2 = 76/2 = 38
heron formula = √s(s-a)(s-b)(s-c) = √78(78-16)(78-35)(78-25) = √78(62)(43)(53) = √11021244 = 3319.82589905≈3319.8in²(nearest tenth)
The answer is: 56xy³

Explanation:
_______________________________
Find the "like terms"; which are:
_______________________________
"4y" and "2y<span>²"
_______________________________
The remaining term is: "7x".
_____________________________________
The problem is a "multiplication problem" :
___________________________________________
7x * 4y * </span>2y² ; so start by multiplying the "like terms" :
<span>___________________________________________
4y * 2y</span>² = 8y<span>³
____________________________________________
Then the remaining term is "7x";
so, multiply that by our obtained value: "</span>8y³ " :
_____________________________________________
7x * 8y³ = 56xy³ ; which is our answer:
