Answer:
x=10;y= -8
Step-by-step explanation:
A: x+y=2
B: -3-y=5 ---> y=-3-5=-8
so
A is : x+(-8)=2
x=2-(-8)=2+8=10
5 x 5 = 25
25 x 6 = 150
150cm^2
Neither. They can’t be parallel because both lines have different slopes. They aren’t perpendicular either because their slopes don’t multiply to equal -1.
Answer:
(3n + 4) (n-2)
Step-by-step explanation:
Are you asking to factor this 3n^2 - 2n -8 ?
If so the best way to do this problem is with the X method.
top: 3*(-8)
left: factor of 3*-8 right: factor of 3*-8
bottom: -2
try the factors 4 and -6 because 4*-6 = 3 *-8 = -24
Because notice that 4 + -6 = -2
so:
3n^2 -2n - 8 can be rewritten as 3n^2 -6n + 4n - 8
We should first use Distributive property to factor: 3n^2 -6n + 4n - 8
3n^2 -6n + 4n - 8 = 3n (n - 2) + 4(n - 2)
Now we factor by grouping here : (3n + 4) (n-2)
I factored out the group (n-2)
Therefore: (3n + 4) (n-2) = 3n^2 -2n - 8
Answer:
He used 5 47 cent stamps and 8 7 cent stamps
subtract 0.47 from 2.91 until you get 0.56 then you begin to subtract 0.07 to get 0.
