F(x) = 3x+2What is f(5)?

Mamont248 [21]

$f(x)=3x+2$

To find f(5) substitute in the equation the x by 5 and evaluate:

$\begin{gathered} f(5)=3(5)+2 \\ f(5)=15+2 \\ f(5)=17 \end{gathered}$ Then, f(5) is 17

PLEASE HELP!!!! WILL GIVE BRAINLEST ANSWER FOR MOST DETAILED

aniked [119]

For

$S= \frac{a+b+c}{2}$
the area is
$area= \sqrt{S(S-a)(s-b)(s-c)}$

find S
S=(10+11+12)/2=(33)/2=16.5
$area= \sqrt{16.5(16.5-10)(16.5-11)(16.5-12)}$
$area= \sqrt{16.5(6.5)(5.5)(4.5)}$
$area= \sqrt{2654.444}$
area=51.5212
rounded
52 square inches

13. What is the value of x?

Scilla [17]

9514 1404 393

Answer:

B. 50

Step-by-step explanation:

The alternate interior angles at transversal t across parallel lines AB and CD will be congruent.

2x +40 = x +90

x = 50 . . . . . . . . . . . subtract x+40

The value of x is 50.

_____

<em>Check</em>

2x+40 = 2×50 +40 = 140

x+90 = 50 +90 = 140 . . . . so the obtuse angles are congruent, as they should be

___

<em>Additional comment</em>

The lines AB and CD are not shown as being parallel. We have to assume they are, or we cannot work the problem.
