Factor completely. b2 + 12b + 32
Factor completely: a2 - a - 20

Answers

Factoring the first polynomial expression completely will give us (b+4)(b+8). Try to check it for yourself by multiplying the factors and you will get b2+12b+32. For the second polynomial expression, the factors are (a-5)(a+4). To check, just do the FOIL method and you will get a2-a-20.

Answer:

b² + 12b + 32 = (b + 8)(b + 4)

a² - a - 20 = (a - 5)(a + 4)

Step-by-step explanation:

b² + 12b + 32

To factor, let's find two numbers that multiply to 32, and add to 12.

I find the two numbers as 4 and 8.

We can expand 12b as 4b + 8b, and factor the pairs.

Factor:

  • b² + 12b + 32
  • b² + 4b + 8b + 32
  • (b² + 4b) + (8b + 32)
  • b(b + 4) + 8(b + 4)
  • (b + 8)(b + 4)

The factored form is (b + 8)(b + 4)

a² - a - 20

Using the same process, find two numbers that multiply to -20 and add to -1

The numbers are 4 and -5

Factor:

  • a² - a - 20
  • a² + 4a - 5a - 20
  • (a² + 4a) + (-5a - 20)
  • a(a + 4) -5(a + 4)
  • (a - 5)(a + 4)

The factored form is (a - 5)(a + 4)

User: 12. Solve this problem: –282 – (+1,017) = ?
A. 1,299
B. –735
C. –1,299
D. 735

Answers

If you would like to solve the equation y/9 + 5 = 0, you can do this using the following steps:

y/9 + 5 = 0
y/9 = -5     /*9
y = -5 * 9
y = - 45

The correct result would be D. y = - 45.


If you would like to solve - 282 - (+ 1,017), you can do this using the following steps:

- 282 - (+ 1,017) = - 282 - 1,017 = - 1,299

The correct result would be C. - 1,299.

On a map, 3 inches corresponds to 100 miles. Find the actual distance between two cities that are 7 1/2 inches apart on the map.

Answers

Check by using law of ratios and proportions:
3 is to 100 = 7.5 is to x
Rule: The product of the means equals the product of the extremes.
3•x = 7.5•(100)
3x = 750
x= 750 : 3
x = 250
