What is the fully simplified form of the expression (-16 x3y - 20 x2 y2 -12 x y3) ÷ 2xy? *Remember to factor each expression completely before dividing.

a
- 8x^2 - 10xy - 6y^2
b
- 8x^2y -10xy -6xy^2
c
- 16x^2 - 10xy - 12y^2
d
- 16x^3y - 10xy - 12xy^3

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
