I will vote u brainliest if u answer so pls do i have 2 questions that im too lazy to answer but they also kinda hard

1. Choose the lower unit price.23. $4.99 for 6 cans or $7.99 for 10 cans

2.$21.50 for 4 pounds of lunch meat or $15.10 for 3 pounds of lunch meat

i want a sure, correct answer otherwise u dont get brainliest

For this, you have to calculate the Unit value,

Unit value of 1rst one,  4.99/6 = 0.83

Unit value of 2nd one, 7.99/10 = 0.79

As, 2nd one is cheaper, so it is better :))

Step-by-step explanation:

Answers are $7.99 for 10 cans and $15.10 for 3 pounds

Step-by-step explanation:

$7.99 for 10 cans is cheaper by .03 and $15.10 for 3 pounds is cheaper by around .25

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

b) 36

step-by-step explanation:

18 times 2 is 36
