2x^2+7x-4=0
2x^2+8x-x-4=0
2x(x+4)-1(x+4)=0
(2x-1)(x+4)=0
So the zeros or solutions occur when x=-4 and 1/2
I'm not sure what you're asking.... but
18+18=36
36 divided by 9 is equal to 4
the answer is 4
Answer:
-m + 2n - 2
Step-by-step explanation:
R - [S + T]
Since we know R = 11 - 2m, S = n + 5, and T = -m - 3n + 8,
we can substitute them in.
Replacing R,S and T
11 - 2m - [n + 5+-m - 3n + 8]
Combine inside the brackets
11 - 2m - [n - 3n-m +5+ 8]
11-2m -[ -2n -m +13]
Distribute the minus sign
11-2m - -2n --m -13
11-2m +2n +m -13
Combine like terms
m-2m +2n +11 -13
-m +2n -2
Answer:
$69
Step-by-step explanation:
Price of book after the price increase
= 60 + 15% of 60
= 60 + 0.15*60
= 60 + 9.0
