Follow the method of rise over run and a is your answer
Simple, use PEMDAS and then do your simple math and then your answer should be 86922.56604
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
Answer:
I do not know
Step-by-step explanation:
I think so
Using the sum (addition) and two 2-digit addends, 12 + 34 can be answered without regrouping.
