Whenever you see <em>x </em> next to a 3, and it says that it equals 9, you know that 3•3=9.
Simplified: 3x+7y+(-2y)+9
Coefficient of y: 5
Constant: 3 and 6
the answer is -10 you just multiply 3 times -2 and then subract 4
Answer:
Step-by-step explanation:
Volume of the cube = s^3
s = 9cm
V = 9 * 9 * 9
V = 729 cm^3
d = mass / volume
d = 3645 / 729
d = 5 grams / cm^3
0.02 times 0.7 = 0.014 all u needed to do was 2 times 7 and add two zeros
