To solve this you would do:

A= a+b x h / 2

Replace variables

A= 5 + 8 x 6 / 2

A= 39cm2

Use the formula: A= (a+b/2)h
A=(8+5/2)6
A=39
The answer is the light blue box, 39cm^2

K is the midpoint of JL JK=3x-1 and KL=2x+8 find JL

Masteriza [31]

Answer:

JL = 52

Step-by-step explanation:

It is given in the question that K is the midpoint of JL.

So, JK = KL ......... (1)

Now, given that, JK =3x - 1 and KL = 2x + 8

Therefore, from equation (1), we can write

3x - 1 = 2x + 8

⇒ x = 9

So, JK = 3x - 1 = 3(9) -1 = 26 and KL = 2x + 8 = 2(9) + 8 = 26

Hence, JL = JK + KL = 26 + 26 = 52. (Answer)

M(x)=1/x f(x)=2x-10 find the domain restriction of m(R(x))

AlexFokin [52]

Answer:

x ≠ 5

Step-by-step explanation:

Given

m(x) = 1/x
f(x) = 2x - 10

Composite function

m(f(x)) = 1/ (2x - 10)

The denominator can't be zero

2x - 10 ≠ 0
2x ≠ 10
x ≠ 5
