Step-by-step explanation:
You could use a calculator if your teacher/instructor lets you! :)
OR you could do long division.
In 1 min the thing can pump 6 gallons of water
Factoring the equation:
3x^2 + 1/2 x 7(3)
3x^2 + 1/2 x 21
3 (x^2 + 1/2 x 21)
3 (x^2 + 7/2)
3 x 1/2 (2x^2 +7)
3/2 (2x^2 + 7)
Step-by-step explanation:
When x = 4,
9x=9×4=36
When x = 7,
9x = 9×7 =63
When x = 2.5
9x = 9×2.5 = 23.5
