Answer:
Option 1
Step-by-step explanation:
3x - 7y = -7y + 3x
They have simply been moved to opposite ends of the equation.
a is correct
Step-by-step explanation:
Area of Bigger rectangle = 4x2 + 5x - 2
Area of Smaller rectangle = x2 + 3× + 5
diff. = ( 4x2 + 5x - 2) - (x2 + 3x - 5)
= 4x2 + 5x -2-x2 - 3x - 5
= 3x2 + 2x - 7
If 6 is halfway between 2.8 and x, then the distance from 2.8 to 6 is 1/2 the distance from 2.8 to something
find the distance
6-2.8=3.2
1/2 distance=3.2
multiply by 2 to find whole distance
3.2 times 2=6.4
add
2.8+whole distance=2.8+6.4=9.2
6 is halfway between 2.8 and 9.2
6 is halfwa between -12 and something
find distance
6-(-12)=6+12=18
1/2 distance=18
times 2
18*2=36
add
-12+36=24
6 is halfway between -12 and 24
blanks are
6 is halfway betwen 2.8 and 9.2
6 is halfway betwen -12 and 24
