Answer:

22 pounds

Step-by-step explanation:

c+s=52, c = 52-s

3c+5s=200

3(52-s) +5s = 200

156 - 3s +5s = 200

5s-3s = 200-156

2s = 44

Shrimp = 44/2 = 22 pounds

Please help, I'm trying to finish these

2 x length + 2 x width = perimeter.

2(2s-5) + 2(4s-13) = 108

Simplify:

4s-10 + 8s-26 = 108

Combine like terms:

12s - 36 = 108

Add 36 to both sides:

12s = 144

Divide both sides by 12:

s = 144/12

s = 12

Now replace s with 12 in each equation:

2(12) - 5 = 24-5 = 19

4(12) - 13 = 48-13 = 35

The answer is d. 35,35, 19,19

What is the principal square root of -4

devlian [24]

Answer:

The principal square root of -4 is 2i.

Step-by-step explanation:

$\sqrt{-4}$ = 2i

We have the following steps to get the answer:

Applying radical rule $\sqrt{-a} =\sqrt{-1} \sqrt{a}$

We get $\sqrt{-4} =\sqrt{-1} \sqrt{4}$

As per imaginary rule we know that $\sqrt{-1}=i$

= $\sqrt{4} i$

Now $\sqrt{4} =2$

Hence, the answer is 2i.
