Answer:

Step-by-step explanation:

Assuming your (f*g)(2) is the product f(2)*g(2), you have ...

f(2) = 8*2 +7 = 23

g(2) = 2+2 = 4

(f*g)(2) = f(2)*g(2) = 23*4 = 92

Help please! Figure JKLM is a parallelogram. The measures of line segments MT and TK are shown. What is the value of MT? A.) 7 B

Zinaida [17]

Hey there! :)

Answer:

C) 74 units.

Step-by-step explanation:

MT is congruent to KT because the diagonals of a quadrilateral bisect each other. Therefore:

8y + 18 = 12y - 10

Subtract 8y from both sides:

18 = 4y - 10

Add 10 to both sides:

28 = 4y

Divide both sides by 4:

28/4 = 4y/4

y = 7 units. Plug this into the equation for MT:

8(7) + 18 = 74 units.

How the answer would end in 15.81

charle [14.2K]

$\bf \sqrt{250}\implies 15.\underline{81}138830084189665999
\\\\\\
\textit{to \underline{two} decimal places is just}\qquad 15.81$

so.... since the number after .81 is 1, it doesn't really round up to .82, so is just that, 15.81.
