Answer:
x=7 and y= 1/3
Step-by-step explanation:
we have -5x - 15 = -30 <=> x + 3 = 10
x= 7
if x=7
so 2×7 - 6y = 12 <=> 14 - 12 = 6×y
2 = 6y
y= 2/6 = 1/3
Obtuse triangle Pythagorean Theorem
c² > a² + b²
20² > x² + 3x²
400 > 4x²
<u>÷4 ÷4</u>
<u> 100 > x²</u>
10 > x
400 > 4(7.1)²
400 > 4(50.41)
400 > 201.64
The greatest possible value of x is 7.10
14/1 or 14 that could be your answer good luck:)
