Answer:
24
-560
Step-by-step explanation:
(1) (-2) * 3 * (-4)
A negative time a negative is a positive
2*3*4 = 24
(iv) 8 x 7*(-10)
This result will be negative since there are positive times negative
8*7 =56* 10 = 560
8*7* (-10) = -560
The variable you wanted to find wasn’t mentioned, so I solved for all three:
5xy + n = 12
5xy = 12 - n
x = 12-n/5y
y = 12-n/5x
n = 12 - 5xy
Depends on where you’re buying. do you have any more details?
Answer:
Tiles won't be enough
Step-by-step explanation:
The perimeter of the area :
2(length + Width)
Given dimension = 6.4 by 2.7 feets
Perimeter = 2(6.4 + 2.7) = 18.2 feets
1 feet = 12 inches
Perimeter = 18.2 * 12 = 218.4 inches
1 tile = 6 inches
30 tiles = 6* 30 = 180 inches
Since the perimeter of the area is greater Than the 180, then we can conclude that the tiles won't be enough
