Step-by-step explanation:

a. (8x³ - 5x² + 4x - 5) - (6x³ - 4x² - x + 2)

= 2x³ - 9x² + 3x - 3

hence, remainder distance is 2x³ - 9x² + 3x - 3.

b. (6x - 3y + 4z - 2m) + (4z - 4y + 5x - 2m)

= 11x - 7y + 8z - 4m

hence, (6x - 3y + 4z - 2m) should be subtracted from (11x - 7y + 8z - 4m) to get (4z - 4y + 5x - 2m)

c. (-1x + 6x² - 2) + (2x² - 3 - 2x)

= 8x² - 5 - 3x

now,

(10x² - 5 + 2x) - (8x² - 5 - 3x)

= 2x² - x

therefore, measure of 3rd side of the triangle is 2x² - x.

e. a² + 1a

f. x(6 - 2x) = 6x - 2x²

g. -2ab ( 3ab² + 2a²b ) = -6a²b³ - 4a³b²

h. -3b

I. -2x

What is the length of DE

HACTEHA [7]

Answer:

DE = 20units

Step-by-step explanation:

In Δ ABC,

angle A is congruent to angle B.... (given)

therefore, ΔABC is an isoceles triangle.

therefore, CA = CB..... (side opposite to congruent angles are congruent in an isoceles triangle)

therefore, CB = 4 units

In ΔCDE,

angle D is congruent to angle E.... (given)

therefore, ΔCDE is an isoceles triangle.

therefore, CD = CE

therefore, CD = 8 units

ΔCDE ~ ΔCBA

therefore,

$\frac{cd}{cb} = \frac{ce}{ca} = \frac{de}{ab} \\ therefore \: \frac{8}{4} = \frac{8}{4} = \frac{de}{10 } \\ therefore \\ \frac{2}{1 } = \frac{de}{10 } \\ de \: = 2 \times 10 = 20units$

Jasper has an annual salary of $71000 and his company pays him twice a month. What is the gross income per paycheck that Jasper

Sliva [168]

Answer:

$2,958.33

Step-by-step explanation:

Jasper's annual salary is $71000.

Considering that a year has 12 months and that he gets a paycheck twice each month, the total number of paychecks (P) Jasper gets each year is:

$P = 12*2 = 24$

To define Jasper's gross income per paycheck (I), simply divide his annual salary by the number of paychecks in a year:

$I=\frac{\$ 71,000}{24} \\I=\$ 2,958.33$

Jasper's gross income per paycheck is $2,958.33.
