Step-by-step explanation:

given,

MP = x - 8

PN = 3x - 9

MN = 21

we know,

according to segment addition postulate AB + BC = AC

now,

MP + PN = MN

→ x - 8 + 3x - 9 = 21

→ 4x - 17 = 21

→ 4x = 21 + 17

→ 4x = 38

→ x = 38/4 = 9

→ x = 9

therefore, value of x is 9.

hope this answer helps you dear! take care

BaLLatris [955]

Answer:

It has two solutions

Step-by-step explanation:

The system $\frac{3}{4z}=\frac{1}{4z-3} + 5$

If we try to simplify the fractions applying the Lesser Common Factor

We obtain this:

$12z-9=4z+ 5(4z)(4z-3)$

From this equation, you can see a square term coming up, from where we can say that this system has two solutions

The midsegment of a trapezoid is 11 cm in length. If one of the trapezoid's bases is 17 cm long, what is the length of the other

vagabundo [1.1K]

Answer:

x must be 5

Step-by-step explanation:

Recall that the area formula for a trapezoid is

A = (average of base lengths)(width)

Here we have

17 cm + x

(average of base lengths) = 11 cm = ----------------

So 2(11 cm) = 17 cm + x, or

22 cm = 17 cm + x

Then x must be 5.
