Answer:

Step-by-step explanation:
Take out 4:
4(x^2-8x)-12
=4(x^2-8x+16-16)-12
=4(x^2-8x+16)-64-12
=4(x^2-4)^2 - 76
=
Answer:
The three numbers are : 9, 9 and 18
Step-by-step explanation:
Since the mean is 12 the sum of the three numbers must be 36. This is because:
(let the three numbers be x y and z)
(x+y+z)/3=12
(x+y+z)=12*3
(x+y+z)=36
And since the mode is 9 two of the numbers must be 9.
So to find the third number;
9+9+z=36
z=36-18
z=18
D = devaugn's age
s = sidney's age
so, we know Devaugh's age is twice as Sydneys, so d = 2*s or 2s
and we know their sum is 66
or d + s = 66
since d = 2s, thus
(2s) + s = 66 <--- solve for "s" to see Sidney's age
what about Devaugn's? well d = 2s
Answer:
(3,-4)
Step-by-step explanation:
3x-7(2x-10)=37
3x-14x+70=37
-11x+70=37
-70 -70
-11x= -33
divide -11 both sides
x= 3
y=2(3)-10
y=6-10
y= -4
