Foils stands for first, outer, inner, last.
For example:
(3x + 5)(2x + 3)
Multiply the firsts together.
3x * 2x = 5x²
Now multiply the outer together.
3x * 3 = 9x
Now multiply the inners.
5 * 2x = 10x
Now multiply the lasts.
5 * 3 = 15
so the answer would be:
5x² + 9x + 10x + 15
5x² + 19x + 15
Hope this helps :)
Step-by-step explanation:
- In a right triangle, if ∠B is 45°, then ∠C is too.
-- Since ∠B and ∠C are equal, the sides opposite them
are equal too. This is an isosceles right triangle. Its legs
are equal.
-- (The hypotenuse)² = (one leg)² + (the other leg)²
= (12-ft)² + (12-ft)²
= (144 x 2)
The hypotenuse = √(144 x 2) = 12√2 .
