Figure abcd is a parallelogram.

a. 44
b. 14
c. 38
d. 49

44 units

Step-by-step explanation:

We know that in a parallelogram opposite sides are equal.

Therefore AB=CD and AD=BC

Consider AB=CD,

⇒4y-2=2y+6

⇒2y=8

⇒y=4

Now consider AD=BC,

⇒3x-1=2x+2

⇒x=3

now substituting values of x and y in the expressions of sides,

we get AB=CD=14 units and AD=BC=8 units

Therefore perimeter of parallelogram is 2*(AB+BC)=2*(14+8)=44 units

easy math just plug in a and b

step-by-step explanation:

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
