Answer:
Expand (2x−7)(2x−7) ( 2 x - 7 ) ( 2 x - 7 ) using the FOIL Method
0.4x + 0.28 = 0.6x - 4.2
0.4 x - 0.6x = - 4.2 - 0.28
- 0.2x = -4.48
x = 22.4
Answer:
1,2
Step-by-step explanation:
6,59-7,8+2,41=1,2
The range would be D is the answer
Since the areas are the same (5 x 6 = 30 units), and the height of the triangle (DC) is 5 so the length of the triangle must be 12. (1/2 of 5 x 12 is also 30)
So now we use the Pythagorean theorem
a² + b² = c² we have 5² + 12² = c² or 25 + 144 = c² or 169 = c²
The square root of 169 is 13 so side DE is 13 units.
