3a(4a^2 - 5a + 12)=12a^3-15a^2+36a (C)
13000000=10000000 (1+0.03)^t
Solve for t
T=log(13,000,000÷10,000,000)÷log(1+0.03)
t=8.9 years round 9 years
Answer:

Step-by-step explanation:
The area of the figure is equal to the area of four right triangles
so
The area of one right triangle is equal to


Multiply by 4

<em>Alternative Method</em>
The figure is a Rhombus
The area of the Rhombus is equal to

where
D1 and D2 are the diagonals of the rhombus
we have

substitute


Answer: $23000
Step-by-step explanation:
The formula for interest will be:
Interest = Principal × Rate × Time
We'll then slot in the values given and this will be:
6900 = Principal × 5% × 6
6900 = Principal × 0.05 × 6
6900 = Principal × 0.3
Principal = 6900/0.3
Principal = 23000
The amount borrowed is $23000
