Answer:
Is 10cm and 6 cm an option
Equilateral: all sides are the same length
isosceles: two sides are the same length
obtuse: there is 1 obtuse angle
Step-by-step explanation:
Take the number as x
12x-40=7x+25
collect like terms
12x-7x=25+40
5x=65(divide both sides by 5)
x=13
Therefore number is 13
Y=2/3x-5
That is the regular slope-intercept form
