Y=3x^2-15x-x+5=3x^2-16x+5
(3x-1)(x-5)
-5(x^2+12+36)+22=-5x^2-24-180+22=
=-5x^2-182
There is nothing here....
Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4
Answer:
Option 4
Step-by-step explanation:
Equating given length and width to the area :
- 8x(5x) = 490
- 40x² = 490
- x² = 490/40
- x² = 12.25
- x = 3.5
Finding the dimensions :
- length = 8x = 8(3.5) = 28 units
- width = 5x = 5(3.5) = 17.5 units
Answer:
30
Step-by-step explanation:
WE use permutation for this question:
since the letters in SQUARE are all distinct, so：
