That is the multipliative identity property.
Solve your equation step-by-step.
5(2y−2)+4=4
Simplify both sides of the equation.
5(2y−2)+4=4
(5)(2y)+(5)(−2)+4=4(Distribute)
10y+−10+4=4
(10y)+(−10+4)=4(Combine Like Terms)
10y+−6=4
10y−6=4
Add 6 to both sides
.
10y−6+6=4+6
10y=10
Divide both sides by 10.
10y/10 = 10/10
No. It would multiply 8 times as much. The old volume is LWH, the new one would be 2L2W2H.
Answer:
3x^2 - 2x + 1
Step-by-step explanation:
first row: 5 (x^2) tiles, -2 (x) tiles and 2 (1) tiles
minus (-) tile
second row: 2 (x^2) tiles and 1 (1) tile
equal (=) tile
ans: 3 (x^2) tiles, -2 (x) tiles and 1(1) tile
3x^2 - 2x + 1
