It is C.
First, you have to do the problem in the (), so 3*4 = (12). 12 - 2 is 10. Next, you do the other () which is 5 + 7 which is 12. 12 + 10 = 22

Area = 3.3998
Perimeter = 2.9
Step-by-step explanation:
A method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle. The area is given by:
Area = √ p ( p − a ) ( p − b ) ( p − c )
where p is half the perimeter, or
a + b + c / 2
p = 1.7 + 1.7 + 2.4 / 2 = 5.8 / 2 = 2.9
a = Area = 3.3998
Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.
Hello!
So, you have to plot the points on the graph.
Your point is (4, -3/4) so, plot the 4 on the x-axis, and the -3/4 on the y-axis.
Go to the right on the x-axis 4 units to get to (4, 0) and from there go <em>down</em> (becuase it is a negative (-3/4)) 3/4 of a unit.
I have attached an image of what it looks like below.
I hope this helps :))
