Simplified answer is: 7xy+4tx
Step-by-step explanation:
3x-4y=13
y=-3x-7
3x-4(-3x-7)=13
3x+12x+28=13
15x=-15
x= -1
y= -3x-7 = 3-7= -4
( -1, -4)

Answer:
<h2>43.3cm²</h2>
Step-by-step explanation:
Area of a Triangle = Base * Height * 1/2
Base = 5
Height = 4.33
Area of a Triangle = 5 * 4.33 * 1/2
Area of a Triangle = 10.825
There are four triangles.
Surface Area = Area of a Triangle * Number of Triangles
Surface Area = 10.825 * 4
Surface Area = 43.3cm²
Acute is the answer ..........
