Evaluate each expression if r= −3, s=4, and t= −7.

saul85 [17]

Answer:

a. $5$

b. $-1$

c. $132$

Step-by-step explanation:

Given:

$r =-3$ , $s = 4$ and $r = -7$

$\sqrt{s} +|r| \\ \sqrt{4} +|-3| \\ 2 +3 \\ 5$

$\frac{s -r}{t} \\ \frac{4 -(-3)}{-7} \\ \frac{4 +3}{-7} \\ \frac{7}{-7} \\ -1$

$2s^3 +r -t \\ 2(4)^3 +(-3) -(-7) \\ 2(64) -3 +7 \\ 128 -3 +7 \\ 132$

mr farmer rectangular land measures 2000 meters by 3000 meters. if he walks around the perimeter of his land, how far does he wa

Travka [436]

Answer:

10000 meters

Step-by-step explanation

To find perimeter you add the length of each side of the shape. Since the land is a rectangle there are two pairs that are parrallel, being 2000 and 3000. Making the distance 2000 + 2000 + 3000+ 3000 = 10000

Hope this helps!

Find the solution of ___ and determine if it is an extraneous solution

Alex

Answer:

x = 14 is an extraneous solution

Step-by-step explanation:

$4\sqrt{x + 2} = -16$

Divide both sides by 4.

$\sqrt{x + 2} = -4$

Square both sides.

$(\sqrt{x + 2})^2 = (-4)^2$

$x + 2 = 16$

$x = 14$

Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.

Check x = 14:

$4\sqrt{x + 2} = -16$

$4\sqrt{14 + 2} = -16$

$4\sqrt{16} = -16$

$4(4) = -16$

$16 = -16$

16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
