Answer:

  • -5, -18
  • -5x -18x
  • (x -3)(6x -5)

Step-by-step explanation:

a) The factors of 90 are ...

  90 = (-1)(-90) = (-2)(-45) = (-3)(-30) = (-5)(-18) = (-6)(-15) = (-9)(-10)

The sums of these factors are -91, -47, -33, -23, -21, -19.

The factor pair with the sum of -23 is of interest here. Those factors are ...

  -5, -18

__

b) -23x = -5x -18x

__

c) The rewritten expression is ...

  6x^2 -5x -18x +15

  (6x^2 -5x) -(18x -15) . . . . group into pairs

  x(6x -5) -3(6x -5) . . . . . . .factor each pair

  (x -3)(6x -5) . . . . . . . . . . factor out the common factor (6x -5)

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of 2.
kifflom [539]

Answer:

x = 29°

The angles are  137° , 116° , 96° , 44° and 147°

Step-by-step explanation:

The sum of the angles of the polygon is given as 540°. The angles are given as 5x – 8°,  4x° , 96° , 44°, 5x + 2. Therefore, the value of x can be found as follows

5x – 8° + 4x°  + 96° + 44° + 5x + 2° = 540°

collect like terms

5x + 4x + 5x - 8 + 96 + 44 + 2 = 540°

14x + 134 = 540°

14x = 540 - 134

14x = 406

divide both sides by 14

x = 406/14

x = 29°

Therefore, the angles are as follows

29 × 5 - 8 = 137°

29 × 4 = 116°

96°

44°

5 × 29 + 2 = 147°

What is the rate of return when 35 shares of Stock A, purchased for $20/share, are sold for $815? The commission on the sale is
wariber [46]

Cost price:-

\\ \sf\longmapsto 35\times 20

\\ \sf\longmapsto 700

  • Commision=$6
  • Total sold price=815+6=823$

Now

Return=823-700=123

Rate of return

\\ \sf\longmapsto \dfrac{123}{700}\times 100

\\ \sf\longmapsto \dfrac{123}{7}

\\ \sf\longmapsto 17.5\%
