Answer:
2x^2+2x+2 or 2(x^2+x+1)
Step-by-step explanation:
C = 2x^2+5x-1
D = x-1
C-3D = (2x^2+5x-1) - 3 * (x-1) =2x^2+5x-1-3x+3 =2x^2+2x+2 = 2(x^2+x+1)
14.8
By the Pythagorean theorem, ...
... x² = 7² + 13² = 218
... x = √218 ≈ 14.7648 ≈ 14.8
If each Watermelon costs $8.96, you can buy two
s
11. sin A = 7/25
cos A = 24/25
tan A = 7/24
$10.50, the difference is $4.50
