Answer:C 5a^2 +70a +240
Step-by-step explanation:
Answer:
45 m
Step-by-step explanation:
Here,
Base (b) = 9m
Height (h) = 5m
Area of parallelogram = b * h. = 9*5. = 45m
Answer:
using the pythagoras theorem the answer is a=3
Step-by-step explanation:
basically in a right angled triangle a² + b² equals c². in this equation c is the number on the hypotenuse (the line opposite the right angle)
and 4 could be a or b it doesnt make a difference so I'll call it b.
because we have c² and b² we work backwards like this:


because 9 is a², we must find the square root to find <em>a</em>

so a equals 3
