Answer:

See below.

Step-by-step explanation:

7x^2 = 343 Divide both sides by 7

7x^2/7 = 343/7

x^2 = 49 Take the square root of both sides.

sqrt(x^2) = sqrt(49)

x = +/- 7

Answers

7
- 7
sqrt(49)
- sqrt(49)

I think the last two are kind of iffy. I'm not sure you can call them solutions, but the question probably assumes they are. If you use all four answers and get it wrong, them submit +7 and - 7.

Answer:x=9

Step-by-step explanation:

The square root is the opposite of squaring a number. When you square a number you times it by itself. So if you square 3 you get 3x3=9. Square root is finding what number you multiply times itself to get 9...

Triangle A B C is shown. Angle A C B is a right angle. The length of the hypotenuse is 20.

kherson [118]

Answer:

The length of BC is needed because it is the side opposite ∠A.

Step-by-step explanation:

Given the right angles triangle as shown in the attachment, we can get sin(A) without using Pythagoras theorem. Instead we will use SOH CAH TOA trigonometry identity.

According to SOH:

Sin(A) = Opposite/Hypotenuse

Sin(A) = |BC|/|AB|

Opposite side of the triangle is the side facing ∠A.

Based on the formula, we will need to get the opposite side of the triangle which is length BC for us to be able to determine sinA since the hypotenuse is given.
