(x + 4) mm <br> What is the value of x according to this picture?

irinina [24]

Answer:

x = 24

Step-by-step explanation:

The angle bisector creates proportional corresponding line segments on either side of it. That is ...

(35 mm)/(56 mm) = (x +4) mm/(44.8 mm)

Multiplying by 44.8, you have

44.8 · (35/56) = x + 4

28 = x + 4 simplify

24 = x subtract 4

Find the LCM of the polynomials.<br> x² - x - 42<br> x2 + x - 56

den301095 [7]

Answer:

x^3+7x^2-50x-336 or (x-7)(x+6)(x+8)

Step-by-step explanation:

Factor each equation.

x^2-x-42= (x-7)(x+6)

x^2+x-56= (x-7)(x+8)

The common factor is (x-7), therefore the other factors of the expressions must multiply to find the common factor.

(x-7)(x+6)(x+8)=x^3+7x^2-50x-336.

I need help with this question. i keep having trouble

nignag [31]

Answer:

Step-by-step explanation:

The angles <JKL, <EKL, and <JKE form a full angle which means their sum is equal to 360:

134 + 21x + 6 + 5x = 360 add like terms

140 + 26x = 360 subtract 140 from both sides

26x = 220 divide both sides by 26

x = 8.4 approximately

to find the angle m<JKL replace x with the value we found.

This is the two that go together, but are separate questions

Option 1)

6a + 8s = 102

14a + 4s = 150

each adult ticket costs 9 dollars

===================================================

Explanation:

6 adult tickets and 8 student tickets bring in $102, so that means 6a+8s = 102

14 adult tickets and 4 students tickets bring in $150, so 14a+4s = 150

The system of equations is

$\begin{cases}6a+8s = 102\\14a+4s = 150\end{cases}$

If we multiply both sides of the second equation by -2, we get this updated system

$\begin{cases}6a+8s = 102\\-28a-8s = -300\end{cases}$

Add the equations straight down

6a+(-28a) = -22a

8s+(-8s) = 0s = 0 ... the 's' terms go away

102+(-300) = -198

So we end up with the equation -22a = -198 and that solves to a = 9 after dividing both sides by -22.

Each adult ticket costs $9

If you want the value of s, then

6a+8s = 102

6(9)+8s = 102

54 + 8s = 102

8s = 102-54

8s = 48

s = 48/8

s = 6

Meaning each student ticket costs $6

Or you could use the other equation

14a+4s = 150

14(9)+4s = 150

126+4s = 150

4s = 150-126

4s = 24

s = 24/4

s = 6

We get the same value of s
