Answer:

a.the length of midsegment of an equilateral triangle with side lengths of 12.5 cm.=12.5/2=6.25cm

b.

sinceUT is the perpendicular bisector of line segment AB, where T is on AB, find the length of AT given AT = 3x + 6 and TB = 42 - x.

than AT=BT

3x+6=42-x

3x+x=42-6

x=36/4=9

AT=3×9+6=27+6=33

c.

since angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.

EH=GH

5y+10=28-y

6y=28-10

y=18/6=3

Which expression is equivalent to 10a + 6? 10(a + 3) 2(5a + 3) 5(5a + 1) 10(a + 1)
Ivenika [448]
Hey there!
We can factor 10a+6 to get our answer.
Remember factoring as the opposite of the distributive property
(i.e factored would by ab+ac and distributive would be a(b+c)).
We can't have <em>a</em> on the outside, since the second term in our expression doesn't contain an that variable.
We take our greatest common factor, or GCF, so it's factored completely.
We have:
2(5a+3).
Hopefully this helps

Answer:

oh hey I gotchu-

first of all you are gonna make that into two rectangle by slicing the top off if that makes sense so you now have a large rectangle (11×12) and a small one (3×8) now you use the area formula for rectangles base×height so the small one becomes (3×8)=24 and the large one is (11×12)=132. now to make them into one shape for the total area you add those two values 132+24=156 so your total area is 156m²
