Step-by-step explanation:

It's really simple..

look

5a2-60a+180

5 (a2 - 12a + 36)

5 (a2 - 6a - 6a +36)

5 ( a(a - 6) -6( a- 6)

5 (a-6)(a-6)

5(a-6)^2

s2 - 256

s2 - 16^2

(s+16) (s-16)

Answer:

Step-by-step explanation:

a² - 12a + 36 = a² + 2*a *6 + 6²

Compare with (x -y)² = x²- 2ab + y²

                      = (a - 6)²

5a² - 60a + 180 = 5 *a² - 5 * 12 * a + 5 * 36

                        =  5 (a² - 12a + 36)

                        =  5 (a - 6)²

256 = 16 * 16 = 16²

a² - b² = (a + b)(a - b)

s² - 256 = s² - 16²

             = (s + 16) (s - 16)

49q² + 42qr + 9r² = 7²q² + 2 * (7q)  * 3r + 3²r²

                              = (7q)² + 2 *7q * 3r  +(3r)²

                              = (7q + 3r)²

Pls help me with this question.
umka21 [38]

Answer: C

Step-by-step explanation:

The equation is in y=mx+b format. The y is the final amount that you will have to pay. The m in this case is the amount of money that you are paying for each individual month (which is $34.99). The x in this case is the number of months you are paying for (which is 1). And b is the starting fee that you have to pay in order to get a membership in the first place (but will not have to pay after the first month). Thus, seeing as there is 1 month's worth of payment and a starting fee tagged on, y would equal the average total cost for the first month of a gym membership.

Help geometry bisecting angles
dusya [7]

Since the angles are bisecting < RSU = < UST

substitution----- 4x+16=9x-9

subtract 4x from both sides----- 16=5x-9

add 9 to both sides-----25=5x

divide by 5 on both sides------ 5=x

The value of x is 5

substitute the value of x in both expressions

1st expression: 4x+16

substitute the value of x------ 4(5)+16= 20+16=36

2nd expression: 9x-9

substitute the value of x-----9(5)-9=45-9=36

< RST= <RSU+<UST

<RSU=36 degrees

<UST= 36 degrees

------------------------------------you have calculated both above-------------------------------------------

m<RST= 36 + 36=72 degrees
