Answer:
Step-by-step explanation:
Left triangle: it has two congruent legs because has an angle of 45 degrees
AB =
cm
the triangle on the the right is half on an equilateral one
BC = 12 cm
CH = 6√3 cm
AC= (6 + 6√3) cm
2p = 6 + 6√3 + 12 + 6√2 = 18 + 6√3 + 6√2 = 6(3 + √3 + √2) cm
Area = [6(1+√3) * 6]/2 = 18(1+√3) cm^2
$45.75 because you take the 2.75 and times it by how may books which is 13 and you get $35.75 then you add your $10 and it will give you $45.75
The expression is 50 + 0.25t.
<h3>How to compute the value?</h3>
It should be noted that from the information, the cell phone costs $50 a month plus $0.25 for each text message (t).
The expression will be:
= 50 + 0.25(t)
= 50 + 0.25t
Therefore, the expression is 50 + 0.25t.
