It is asking you for the area of the rectangle which you can get by multiplying the length by the width. So 12 * 8 = 96
Answer:
x = 9 and y = -7
Step-by-step explanation:
given:
using substitution method:
2(-4y - 19) + 2y = 4
-8y - 38 + 2y = 4
-6y = 42
y = -7
Solve for x:
x = -4(-7) - 19
x = 28 - 19
x = 9
Answer:
c) a ( b + c ) = (a + b ) + c
Step-by-step explanation:
The associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.
The problem can be translated into an equation that is something like 4/5 + 3/x = 1/2
we cannot have x equal to zero because the number can be infinite.
So the LCD here is 10x, so multiply both sides by that to get:
8x + 30 = 5x
Subtract 5x and 30 from both sides:
3x = -30
divide:
x = -10
The solution isn't zero so there is a solution.
