Step-by-step explanation:
l = length
w = width
l = 3w
perimeter p = 2l + 2w = 56
using the identity of the first equation
p = 2(3w) + 2w = 56
6w + 2w = 56
8w = 56
w = 7 cm
l = 3w = 3×7 = 21 cm
so, the area is
l×w = 21×7 = 147 cm²

a minus sign.
what is 7.69/43.685=?
Answer:
The Correct Answer is 5.6 :)
Step-by-step explanation:
Change the divisor 7.69 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
4368.5 ÷ 769 = 5.6
and therefore:
43.685 ÷ 7.69 = 5.6
Both calculated to 1 decimal places.

General Formulas and Concepts:
<u>Algebra I</u>
- Expand by FOIL-ing (First, Outside, Inside, Last)
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x
g(x) = x - 3
<u>Step 2: Find f(x)g(x)</u>
- Substitute: f(x)g(x) = 2x(x - 3)
- Distribute 2x: f(x)g(x) = 2x² - 6x
