Answer: (x + 12)(x + 18)

Step-by-step explanation: x² + 30x + 216​

                                              12 + 18 = 30

                                              12 x 18 = 216

                                              (x + 12)(x + 18)

Select the correct similarity statement.
Nostrana [21]

Answer:

∆STR ~ ∆RTQ

Step-by-step explanation:

For two fugures to be considered similar, it means the corresponding sides are proportional, and as such, the ratio of their corresponding sides are equal.

However, the corresponding angles of two similar figures are the same and equal.

Taking a look at the figure of the triangle given, ∆STR is a right angle triangle, and it is similar to ∆RTQ as the angle formed at <T in ∆RTQ = 90°.

<T in ∆STR = <T in ∆RTQ.

Therefore, the correct similarity statement is ∆STR ~ ∆RTQ.

The last option is correct.

Assignment: Using Prime Factorization Investigation
damaskus [11]

Answer:

  1. 3(2 +7)
  2. 9(3 +5)
  3. 16(2 +3)
  4. 15(2 +5)
  5. 8(11 +3)

Step-by-step explanation:

  1. 6 + 21 = 2·3 + 3·7 = 3(2 +7)
  2. 27 + 45 = 3^3 + 3^2·5 = 9(3 +5)
  3. 32 + 48 = 2^5 + 2^4·3 = 16(2 +3)
  4. 30 + 75 = 2·3·5 + 3·5^2 = 15(2 +5)
  5. 88 + 24 = 2^3·11 +2^3·3 = 8(11 +3)

In each case, the factor outside parentheses is the greatest common factor, the product of the prime factors common to both numbers. When the same factor has different powers, the least power is the common factor.

How do I convert 75 feet/second to miles/hour rounding to the nearest whole number
MAVERICK [17]

Answer:

51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.

Step-by-step explanation:

Given:

75 feet/second.

Now, to convert 75 feet/second into miles/hour.

So, to convert we divide the value of feet per second by conversion factor to get miles per hour.

Value of feet per second = 75.

Conversion factor = 1.4667.

Now, putting the formula to get the value in miles/hour:

Value in miles/hour = value of feet/second ÷ conversion factor.

Value in miles/hour = 75\div 1.4667.

                                 = 51.135\ miles/hour.

<em>Rounding nearest to whole number = 51 miles/hour.</em>

Therefore, 51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.
