The area of a triangle is:
A=hb/2 where h=height and b=base
We can let the "height" be the horizontal magnitude, (x3-x1)
And the base would then be the vertical magnitude, (y2-y1)
So the area is:
A=(1/2)(y2-y1)(x3-x1)
Well we know the algae doubles three times.
So take 50 x 2 = 100
take 100 x 2= 200
200 x 2 = 400
So the answer is A
I didn’t have enough room to show the solving steps but if you input the equations on the app called photomath you can copy down the steps, in the meantime there’s the answers and code solved, hope this helps!!
Answer:
22.32
Step-by-step explanation:
First you subtract what in the parenthesis 10.75 minus 3.55 equals 7.2
Then you multiply 7.2 by 3.1 which equals 22.31
remember PEMDAS!
Answer:
d=-18
a=51
x=-4
c=13/3
Step-by-step explanation:
1. subtract 6 from both sides
divide both sides by -2
2. add 2 to both sides
times both sides by 3
3. times both sides by 4
divide both sides by 9
4. multiply the 10 out into the parenthesis add the 10c and 2c to get 12 c
add 40 to both sides
divide both sides by 3
