The formula is
A=p (1+rt)
A future value
P present value
R interest rate
T time

Rose investment
A=2,600×(1+0.041×9)
A=3,559.4

Dennis investment
A=2,200×(1+0.057×9)
A=3,328.6

Rose investment is greater by
3,559.4−3,328.6=230.8

So the answer is A

Hope it helps!

Find three consecutive even integers that sum up to -48
Igoryamba
We can write the equation: x + x + 2 + x + 4 = -48, where x is the least digit and x + 4 is the greatest. We get 3x + 6 = -48, 3x = -54. x = -18, so x + 2 is -20, and x + 4 is -22. Therefore, the 3 consecutive even integers that sum to -48 are -18, -20, and -22.

on the left side of the triangle, it says 10 cm, on the right side of the triangle, it says 18 cm, below the triangle, it says 1
stira [4]
Area formula for a triangle is 1/2BxH

B=15
H=10

1/2(15)= 7.5

7.5 x 10= 75

So the area is 75 square cm :)
