Answer:

13. c,

14. a.

Step-by-step explanation:

13. The length of a side PQ with coordinates of

P as (x,y) and Q as (w,z)

is: $\sqrt{(x-w)^{2} +(y-z)^{2} }$

so, the length of the side AB =

$\sqrt{(5-5)^{2}+(-2+7)^{2} } =\sqrt{0^{2}+5^{2} } =5$

the length of side BC =

$\sqrt{(5-1)^{2}+(-7+2)^{2} } =\sqrt{(4)^{2}+(-5)^{2} } =\sqrt{4^{2}+5^{2} }$

the length of side AC=

$\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4$

now, the easiest one will be when the vertices are on the coordinate axes.

so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

here, the alternate interior angles are angle1 and angle4.

therefore to prove this step, he used parallel postulate as a reason.

so, the correct option is "a"

In minutes it is 1500 min because if you just multiply 25 and 60 it equals 1500. I got the 60 from 60 sec. in one minute.

Answer:

28. the second and third one

29. 687.50 dollars

Step-by-step explanation:

2.49(2) + 1.79(2) + 0.89(4) = 12.12 no

2.49(3) + 1.79(2) = 11.05 yes

2.49(2) + 1.79(3) + 0.89 = 11.24 yes

2.49(4) + 1.79 + 0.89 = 12.64 no

area = length times width

a = 6.25 times 5

a = 31.25 square feet

31.25(22) = 687.50
