Answer: 2x(3+4)
Step-by-step explanation: 2x represents the one scoop of food twice a day, and 3+4 represents her 3 cats and 4 dogs.
Volume is the product of the three dimensions...
V=xyz in this case:
V=3*10*5
V=150 yd^3
Do you have multiple choice? If so maybe this is the answer : 5(2x^2+1)
15
(2 + 5) - (2 x -4) = 15
7 - -8
Minus a negative goes upwards.
15
