Answer:
(1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)
Step-by-step explanation:
2.25 = 9/4
putting decimals into fractions will make this easier
9/4 = 3/2 * 3/2
a²-b² = (a+b)(a-b)
1 - 2.25x^8 = 1²-(3/2x^4)² = (1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)
40% of 25 is 10 and 10+25 is 35 so the answer to your question is 35<span>°F</span>
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
Answer:
(3x - 3)(x + 2)
Step-by-step explanation:
3x^2 + 3x - 6
(3x^2 + 6x)(-3x - 6)
3x(x + 2) -3(x + 2)
(3x - 3)(x + 2)
