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.

Answer:

-1/60

Step-by-step explanation:

$\frac{11}{15} + (- \frac{3}{4} )\\$

= $\frac{11}{15} - \frac{3}{4}\\$

= $\frac{44}{60} - \frac{45}{60}\\$ (find LCM of demoninators)

= $\frac{44-45}{60}\\$

= $\frac{-1}{60}\\$

= -1/60
