Answer:
255+35-75
Step-by-step explanation:
Since we are trying to find the account balance, we consider anything in or going to the account to be positive.
255 is positive since it is in the account
35 is positive since it is going into the account
75 is negative because it is going out of the account
so the final expression to express the amount is the checking account would be 255+35-75

Answer:
D. 12
Step-by-step explanation:
There are a number of ways to find the area of this rectangle. Perhaps the most straightforward is to find the lengths of the sides and multiply those. The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the two upper-left points, we find the length of that side to be ...
d = √((3 -0)^2 +(3 -0)^2) = √(9 +9) = √18 = 3√2
Similarly, the length of the lower-left side is ...
d = √((-2 -0)^2 +(-2 -0)^2) = √(4+4) = √8 = 2√2
Then the area of the rectangle is ...
A = LW
A = (3√2)(2√2) = 3·2·(√2)^2 = 3·2·2 = 12
The area of rectangle ABCD is 12.
_____
Other methods include subtracting the area of the corner triangles from the area of the bounding square:
5^2 -2(1/2)(3·3) -2(1/2)(2·2) = 25 -9 -4 = 12
So the answer to this question is:
A= bees: f(t) = 1500 × (0.88)∧t
plants: g(t) = 800 - 25×t
B: (Bees) 1500 × (0.88)∧6= 696.60
After 6 months (696 bees ):
800 - 25×6 = 650 (Flowering Plants)
After 6 months:
650 flowering plants
C: 1500 × (0.88)∧t=800 - 25×t
t = 6.779965672
Answer is it will take 7 months or 6 for the bees and the plants.
Hope this helps!
