P = 2L + 2W

P - 2W = 2L

(P - 2W) / 2 = L

Answer:

D) x = √5

Step-by-step explanation:

$\sqrt{x^{2}+4 }-1 = 2$

$\sqrt{x^{2}+4 } = 3$

$x^{2}+4 = 3^{2}$

$x^{2}+4 = 9$

$x^{2} = 9 -4$

$+x = \sqrt{5} , -x = \sqrt{5}$

8i-(12-4i)+7√-9<br><br> show work please

Tanya [424]

Answer:

33i - 12

Step-by-step explanation:

$8i - (12 - 4i) + 7 \sqrt{ - 9} \\ = 8i - 12 + 4i + 7 \sqrt{9 \times ( - 1)} \\ = 12i - 12 + 7 \times 3 \sqrt{ - 1} \\ = 12i - 12 + 21i \: \: ( \because \sqrt{ - 1} = i)\\ = 12i + 21i - 12 \\ \therefore \red{ \bold{8i - (12 - 4i) + 7 \sqrt{ - 9} }= \purple{ \bold{33i - 12}}}$

Please help me on this I’m super stuck

Answer:

<u>BC = 3.1666</u>

Step-by-step explanation:

To solve this you need to know that cosine∅ = adjacent/hypotenuse. We already know that hypotenuse = 5 and that ∅ = 70*. By substituting these in you will get cosine 70* = adjacent/5. Evaluate cosine 70* on the calculator and get 0.633... Multiply both sides by 5 and get adjacent is about equal to 3.1666. Because BC is the adjacent side of the triangle, this is the length of BC.
