Answer:
A = (12h x b1) + (12h x b2)
A = 12hb1 + 12hb2
A - 12hb1 = 12hb1 - 12hb1 +12hb2
A - 12hb1 = 12hb2
(A - 12hb1) / (12h) = (12hb2) / (12h)
b2 = (A - 12hb1) / (12h)
Answer:
Step-by-step explanation: Not too sure how to explain it this is how you simplify it pretty sure
2x-y=7
+2x +2x add to both sides to get y alone because it has no friends
___________
-y=7+2x get rid of the negative on the y value
__________
y= -2x -7
Answer:
17/18
Step-by-step explanation:
2
/18 + 15
/18
= 2
/18 + 15/
18
= 2+15
/18
= 17
/18
Answer:
11x-y or 5x+y.
Step-by-step explanation: I hope this helps, I really don't know what the question means, since it not that specific.
you can just split the figure in 2 separate figures and them add the areas:
area rec. 1:
3m×3m= 9m²
area rec. 2:
3m× (2m+3m)
= 3m×5m
=15m²
total area:
9m²+15m²= 24m²
