I will pick the brainiest! Thanks! :) Please give a real answer!

37 not 100% sure

Step-by-step explanation: so we know the the measurements of some of the sides on this shape, lets find the sides we don't know first.

so the first measurement is 7.5 we can put 7.5m on the side farthest to the left because there equal lengths and we could also put 7.5 on the line that draw to make two shapes.

so that right there is 7.5x3 = 22.5

now we add the existing measurements

22.5+ 4+2+.5 = 29m

now last we have to found the measurement of the bottom line of the shape. so we know the top line is 7.5 we can add the line .5cm to the top for it to be equal in length at the bottom. so 7.5+.5= 8, therefore the bottom line is 8m

29+8= 37m

again i am not completey sure this is correct but this is what i remeber when trying to find the perimeter of a polygon. goodluck :)!

part d

step-by-step explanation:

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
