Answer:
-3
Step-by-step explanation:
-2(5x+1)=58+10x
=>-10x + -2 = 58 + 10x
=> -10x -10x = 58 + 2
=> -20x = 60
=> x = 60/-20
=> x = -3
Answer: 6 cm
Step-by-step explanation:
Use equation for area of triangle
A=a*h/2
a*h=2A
a=2A/h
where a represents base of triangle
h represents height of triangle.
h=12.8 cm
A=38.4 cm²
a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm= 6 cm
