Explanation: Use "FOIL" technique: (First, Outer, Inner, and Last Terms);
then, combine the "like terms", to simplify.
__________________________________________
(5x+4)(9x+9) = 45x² + 45x + 36x + 35 = 45x² + 81x + 36 .
(which is answer choice: "A".).

It should be ten times greater since,
700x10=7000
So ten times greater.
To generate the equation we set up the factors
(x+3) * (x-1) * (x-2) which equals
x^2 + 2x -3 * (x-2)
x^3 +2x^2 -3x -2x^2 -4x +6 equals
x^3 -3x -4x +6 which equals
x^3 -7x +6
Answer:
2456.8
Step-by-step explanation:
J=×
9×1=2+3'5
f=2456.8
Hi there, 3 feet + 2 feet= 5 feet and 9 inches + 11 inches = 20 inches.
