Answer:

5.  s ÷ 10, 8b, h + 7, 3r - 8

6. 248

Step-by-step explanation:

5.s divided by 10 would be written as s ÷ 10. 8 times b would be written 8b or 8 x b. 7 more than h would be written h + 7 because you are doing 7 more that h not h more than 7. 8 less than the product of 3 and r is written 3r -8 because the word product means to multiply. So, the question is 8 less than 3 times r which is written 3r -8 or (3 x r) - 8.

6. is 248 because if you drive 62 miles each hour and you drive for four hours you will go 248 miles in total. You just multiply 62 times 4.

Hope this helped.:)

Find an integer value of b that makes x^2 + bx - 81 factorable.
Kaylis [27]

Answer:

b = 80

Step-by-step explanation:

Given that,

x² + bx - 81

To find,

value of b

What is factorable?

A polynomial equation with highest degree 2 is if factorable when

  1. we can find two terms which when multiples = -81x²,   <em> ( x² * - 81 = -81x² ) </em>
  2. and when add = bx

possible factors:

  1. -1x * 81x = -81x²   (Accepted)
  2. 1x * -81x= -81x²    (rejected)
  3. 9x * -9x = -81x²    (rejected)
  4. -9x * 9x = -81x²    (rejected)

Only when -1x , 81x is added -1x + 81x = 80x

so, bx = 80x

     b   = 80

<h3>The equation is x² + 80x - 81</h3>
