Answer:</h3>
- $2693.12
- $2125.00
- B) The area of the field is 10.24 times the area of the playground
<h3>
Step-by-step explanation:</h3>
1. Each year the balance is multiplied by 1.09, so after 5 years, the balance is multiplied by 1.09^5 ≈ 1.53862395. Subtracting the original invetment amount gives the value of the interest earned.
... 5000 × 1.53862395 - 5000 = 5000 × 0.53862395
... ≈ 2693.12 . . . . matches choice D
2. The interest earned is given by the formula ...
... I = Prt . . . . . where P is the principal, r is the interest rate, and t is the time period.
Filling in the given numbers, you have ...
... I = 2500×0.085×10 = 2125 . . . . matches choice B
3. The product of length and width is the area. If both length and width are multiplied by 3.2, then the area is multiplied by 3.2×3.2 = 10.24. The appropriate choice is B.

8R + 48 - 2R,
The result is 6R + 48</span>
x² + bx - 81
there are 2 formula that fit this equation :
>> x² - a² = (x+a)(x-a)
or
>> x² + 2ax² + a² = (x+a)(x+a)
because the last value of our equation is negative value therefore we have to use the first formula >> x² - a² = (x+a)(x-a)
step:
x² + bx - 81
x² + bx - 9²
because we have to follow the first formula x² - a² therefore bx = 0
x² + bx - 9²
bx = 0
b = 0
Answer: Simply the expression = 5
Step-by-step explanation:
Simplify = 5
Check if there is a giggle throughout the full equation, since there isn’t, we group the equation and we get
(4ax-10bx)+(6ay-15by)
Factor out the gcf of the two groups
2x(2a-5b)+3y(2a-5b)
Not sure how to explain this step in words but so do this
(2x+3y)(2a-5b)
The solution is (2x+3y)(2a-5b)
