Answer:
68 cm
Step-by-step explanation:
√289 = 17
each side is 17 cm
17 * 4 = 68 cm
6x + 12y = 7
12y = -6x + 7
y = -6/12 + 7
y = -1/2 + 7
the slope of the equation is -1/2
i beilive this is unknown
The answer is 0.746 because thousands is the third number after the decimal point and you are rounding up because 7 is greater than 5
