Answer:

The missing term is 3x

Step-by-step explanation:

Given

-(x - 1) + 5 = 2(x + 3) - _

Required

Find _

For proper identification of the parameters, represent _ with Z

So, the equation becomes

-(x - 1) + 5 = 2(x + 3) - Z

Open bracket (start from the left hand side)

-x + 1 + 5 = 2(x + 3) - Z

-x + 1 + 5 = 2x + 6 - Z

Solve like terms

-x + 6 = 2x + 6 - Z

Subtract 6 from both sides

-x + 6 - 6 = 2x + 6 - 6 - Z

-x = 2x - Z

Subtract 2x from both sides

-x - 2x = 2x - 2x - Z

-3x = -Z

Multiply both sides by -1

-3x * -1 = -Z * -1

3x = Z

Reorder

Z = 3x

Hence, the missing term is 3x

A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round answers to nearest tent
AlexFokin [52]

Answer:

39.275

Step-by-step explanation:

the diameter of the semicircle is 10

A semicircle is half a circle, and a quarter circle is 1/4 of a circle.

Perimeter of a semicircle is ¶d/2

= 3.142 x 10/2 = 3.142 x 5 = 15.71

For 2 semicircles that will be 15.71 x 2 = 31.42

For the quarter circle, perimeter is ¶d/4 = 3.142 x 10/4 = 3.142 x 2.5 = 7.855

Total perimeter = 31.42 + 7.855 = 39.275

Divide. HELP ASAP PLEASE!!
VashaNatasha [74]

Answer:

The answer to your question is below

Step-by-step explanation:

a)                             \frac{s^{2}- 3s - 28 }{s - 7}

Factor the numerator is a polynomial of the form    x² + bx + c

                                              s² - 3s - 28 = (s - 7)( s + 4)

Substitute

                               \frac{(s - 7)(s + 4)}{(s - 7)}

Simplify like terms

Result                                               s + 4

b)                          \frac{c^{2} + 5c - 24}{c + 8}

Factor the numerator is a polynomial of the form x² + bx + c

                                           c² + 5c - 24 = (c + 8)(c - 3)

Substitute

                                          \frac{(c + 8)(c - 3)}{c + 8}

Simplify like terms                            c - 3

Result                                                c - 3
