Since the area of a triangle is in the form
area=0.5(base)(height)
height=base+7
let base=x
area=0.5(x)(7+x)
30=3.5x+0.5x^2
multiply the equation by 2
60=7x+x^2
subtract 60 from both sides
x^2+7x-60=0
(x-5)(x+12)=0
thus x=5 or x=-12 since we are only considering positive answers
x=-12 is rejected
so base=5 and height=5+7=12
The answer
2
Explanation
The median is the middle number and if you take off one side from the left and one side from the right until you have your middle number
Answer:
Y=-2/3x+6
Step-by-step explanation:
Y=-2/3x+b
2=-2/3•6+b
2=-4+b
6=b
