Answer:
It’s c in egd
Step-by-step explanation:
40
Yea. Hope this helps? Adios
discriminant = 0
The real root -2/3
The formula for discriminant : b^2 - 4ac
12^2 (-4)×9×4 = 144 - 144 ➡ discriminant = 0 this means the roots is a repeated real number, which means there's only one solution
(3x + 2) × (3x + 2) = 0
3x+ 2 = 0
x = -2/3
2.5
25 / 10 = 2.5
Check with 6in
6 x 2.5 = 15
the volume is 0.8 × 0.3 × 1.3 = 0.312 units cubed.
After scaling down 1/10:
Length = 8 ÷ 10 = 0.8
Width = 3 ÷ 10 = 0.3
Height = 13 ÷ 10 = 1.3
