2r2 + 3s3 − r2 + 4t2 − r2 if r = −2, s = −3, and t = 5.

Elza [17]

First, simplify the expression $2r^2 + 3s^3 - r^2 + 4t^2 - r^2.$ Here you have three terms with $r^2,$ group them in the following way:

$2r^2 + 3s^3 - r^2 + 4t^2 - r^2=2r^2-r^2-r^2+3s^3+4t^2=(2r^2-r^2-r^2)+3s^3+4t^2=$

$=r^2(2-1-1)+3s^3+4t^2=3s^3+4t^2.$

Then substitute s=-3 and t=5:

$3s^3+4t^2=3\cdot (-3)^3+4\cdot 5^2=3\cdot (-27)+4\cdot 25=-81+100=19.$

Answer: 19.

HELP PLSSS ASAP!!!!!!!!

neonofarm [45]

Answer:

x = 5.5

Step-by-step explanation:

PM = MR

4x - 12 = -2x + 21 {add 2x to both the sides}

4x - 12 + 2x = -2x + 2x + 21

6x - 12 = 21 {Add 12 to both sides}

6x - 12 + 12 = 21 + 12

6x = 33

x = 33/6

x = 5.5
