Answer:
x² + 9x + 20
Step-by-step explanation:
Area of a rectangle can be found by multiplying the base with height (or length with width).
A(r) = l x h.
Multiply. Plug in:
x + 5 for l
x + 4 for h
A(r) = (x +5) * (x + 4)
Use the FOIL method to solve. Multiply the first terms of both parenthesis, the outside terms, the inside terms, and then the last terms. Combine like terms:
A(r) = (x + 5) * (x + 4)
x * x = x²
x * 4 = 4x
5 * x = 5x
4 * 5 = 20
x² + 4x + 5x + 20
x² + (4x + 5x) + 20
x² + 9x + 20
x² + 9x + 20 is your answer.

This simple interest calculator calculates an accrued amount that includes principal plus interest. The equation is <span>A = P(1 + rt). Given the details provided, </span>A = $ 885.00
The calculation: First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year, then, solving our equation
A = 750(1 + (0.06 × 3)) = 885
A = $ 885.00
The total amount accrued, principal plus interest, from simple interest on a principal of $ 750.00 at a rate of 6% per year for 3 years is $ 885.00.
34 i think cuz it goes up by 2 4 6 and it repeats it self
Just do 3.14+3.14 times the height
