Can you provide imformation on how many different areas that it can land on?
Answer:
Step-by-step explanation:
7) 2ab + 4ac = 2*a*b + 2 *2 *a*c
= 2a(b + 2c)
8) ac - a²c² = c( a - a²c)
bc - abc = c(b - ab)
9) b²+ 4b - 5 = b² + 5b - 1b - 5
= b(b + 5) - 1(b + 5)
= (b +5)(b - 1)
b² + 8b + 15 = b² + 5b + 3b + 15
= b(b + 5) + 3(b + 5)
= (b + 5 )(b + 3)
Answer:
3.6cm cubed
Step-by-step explanation:
First solve for both glasses' volumes.
Use l×w×h to plug in the numbers:
3.1×2×3=18.6
3.7×2×3=22.2
then subtract= 3.6
Answer:
x=-2
Step-by-step explanation:
-2x-7=3(4x+7)
distribute
-2x-7 = 3*4x +3*7
-2x-7 = 12x+21
add 2x to each side
-2x-7+2x = 12x+2x+21
-7 = 14x+21
subtract 21 from each side
-7-21 = 14x+21-21
-28 = 14x
divide by 14
-28/14 = 14x/14
-2 =x
