The formula you use is a^2 + b^2 = c^2

Let's set up the equation 30^2 + 42^2 = c^2

a and b are ALWAYS the legs of the triangle. c is ALWAYS the hypotenuse. 
Since you're finding c, the shadow's length, then we leave that as c instead of plugging in a number.

Next, find the square of 30 and 42, to leave the equation: 
900 + 1,764 = x^2
add 900 + 1,764 to make 2,664.

2,664 = x^2 is what we're left with.

All you need to do now is square root 2,664 to find x instead of x^2

x = 51.614

Your answer is the last one, 51.6 feet.

Answer:

A) x = 15

Step-by-step explanation:

4x - 30 = 2x

subtract 2x from each side of the equation:

2x - 30 = 0

add 30 to each side:

2x = 30

x = 15

Multiplethinker9, DO. NOT. ANSWER.
ruslelena [56]

A feature of every linear function is that the slope is the same no matter where you are on the line. When given a table of data that you suspect might represent a linear function the slope manifests itself as a constant common difference between successive y -values.

7(5x + 9) = 12 - (x +9)
den301095 [7]

Answer:

\frac{-5}{3} is the answer

Step-by-step explanation:

7(5x+9)=12+−1(x+9)(Distribute the Negative Sign)

7(5x+9)=12+−x+−9

(7)(5x)+(7)(9)=12+−x+−9(Distribute)

35x+63=12+−x+−9

35x+63=(−x)+(12+−9)(Combine Like Terms)

35x+63=−x+3

Add x to both sides.

35x+63+x=−x+3+x

36x+63=3

subtract 63 from both sides.

36x+63−63=3−63

36x=−60

Divide both sides by 36.

\frac{36x}{36} =\frac{-60}{36}\\

-5/3 is the answer.

ik this doesnt make any sense but hope this helps
