Answer:
9.423 rounded to the nearest one is 9
Step-by-step explanation:
Using elimination method to find y
3x - 4y = -15 (multiply 4)
4x + 3y = 5 (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y = 15
--------------------- - (substract)
-25y = -75
y = 3
Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1
The solution (-1,3)

I hope this is good enough:
The area of the triangle XYZ is 29.1 square units
Explanation:
Given that the measurements of the sides of the triangle XYZ are
,
and 
We need to determine the area of the triangle XYZ
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,

Substituting the values, we get,

Simplifying, we get,

Multiplying the terms, we get,

Dividing the terms, we have,

Rounding off to the nearest tenth, we get,

Thus, the area of the triangle XYZ is 29.1 square units.
