Answer:
2z-6
Step-by-step explanation:
2(z-3)
2(z)-2(3)=2z-6
If you mean distance, then we can use the distance formula to find out.
(x - x)² + (y - y)² = d² Distance formula
(-2 + 2)² + (7 + 6)² = d² Substitute the points; remember that when you subtract a negative, you add, and also remember to always subtract in the same direction (with the points (1,2) and (3,4), if you do 1 - 3, then do 2 - 4 and not 4 - 2)
(0)² + (13)² = d² Add
0 + 169 = d² Square
169 = d² Add
13 = d Take the square root of both sides to cancel out the exponent
The distance between (-2,7) and (-2,-6) is 13 units.
Hope this helps!
Answer:
Step-by-step explanation:
if x= -2
and P(x)=x^4+4x^3+6x^2-8
then P(-2)=(-2)^4+4*(-2)^3+6*(-2)^2-8=16-32+24-8=0
so P(x)=(x+2)* Q(x) and P(x) is divisible by x+2
Answer:
(3x^2 + 1) (4x – 3)
Step-by-step explanation:
12x³– 9x² + 4x – 3 in factored terms;
First, find the GCF of 12x³– 9x² + 4x – 3
3x²is a common factor in 12x³ and 9x²
we have 3x² (4x – 3) + 4x – 3
Splitting the expression into 2 groups 3x² (4x – 3) + ( 4x – 3)
4x – 3 is a common factor in both groups
Factoring 4x – 3, we have
3x² (4x – 3) + (4x – 3)
Therefore, in factored form, the equation becomes (3x² + 1) (4x – 3)
