Mathematics

You need to use PEMDAS or the Order of Operation. P is parentheses, E is exponents, M is multiplication, D is division, A is addition, and S is subtraction. 8+5 is 13. There are No exponents or multiplication. Divide 13 by 1 and you get 13. So far, you have 1 + 13 - 3 - 13 + 4. If you do the addition you get 18 - 3 -13. 18 - 3 is 15. 15 - 13 is 2. Your answer is 2.

Given DEF : RST, find the scale factor.<br><br> PLEASE HELP!
Elena L [17]

9514 1404 393

Answer:

  • scale factor 3 : 4
  • x = 12

Step-by-step explanation:

To find the scale factor from ΔDEF to ΔRST, find a measure on ΔDEF and a corresponding measure on ΔRST, then write them in the form required for the scale factor.

Here, there are numbers on DE, RS, and ST. We see by the similarity statement ΔDEF ~ ΔRST that DE corresponds to RS, so the scale factor is ...

  ΔDEF : ΔRST = DE : RS = 3 : 4 . . . scale factor

__

Using that scale factor, you can write a proportion to find the value of x.

  3 : 4 = x : 16  ⇒  3/4 = x/16

Multiplying the fraction equation by 16, we have ...

  x = 16(3/4)

  x = 12
