− 14x/ 3 i think this would be the answer
Answer:
Step-by-step explanation:
the side of equilateral triangle = a
so, area =
=》
y + 4 = 14(x - 12)
y + 4 = 14x - 168
y = 14x - 168 - 4
y = 14x - 172
0,8 cm on the map is equal to 8 m in real life
Step-by-step explanation: x + 1 = 9x - 3
x + 1 = 9x - 3
(minus x from both sides)
1 = 8x -3
(add 3 to both sides)
4 = 8x
(flip the equation)
8x = 4
(divide both sides by 8)
x = 4/8
x = 1/2 or 0.5
