Answer:

25 mm

Step-by-step explanation:

Set up a proportion where x is the number of millimeters for 160 kilometers

\frac{5}{32} = \frac{x}{160}

Cross multiply and solve for x:

32x = 800

x = 25

So, 25 millimeters represent 160 kilometers

Angle A= 6x+18 degree
Oksanka [162]

Answer: Hello and welcome to brainly, The answer for this question is Angle A = B

A = 6x + 18

B =  x + 93

A = B

Solve for x

6x + 18 = x + 93

6x - x = 93 -18

5x = 75

5x/5 = 75/5

x = 15

x = 15

Insert 15 into our equations.

6(x)+ 18  = ?

6(15)+ 18  = 108

x + 93 = ?

15 + 93 = 108

Answer = 108

5. x2 +5x-4<br> Discriminate
ikadub [295]

Answer:

<em>D = 41</em>

Step-by-step explanation:

y = ax² + bx + c

The discriminant D = b² - 4ac tells the types of roots the equation has.

If D < 0 , then quadratic equation has no real roots, has two imaginary roots.

If D = 0 , then quadratic equation has one real root.

If D > 0 , then quadratic equation has two distinct real roots.

~~~~~~~~~~~~

x² + 5x - 4

a = 1, b = 5, c = - 4

<em>D </em>= 5² - 4(1)(- 4) = 25 + 16 =<em> 41</em>
