Hi there! To solve this question, we can write and solve a proportion. We put shadow/height = shadow/x. We do this, because we're looking for the height of the pole and we already know the how big the shadow of the pole is. The yards need to be converted to feet. There are 3 feet in one yard and 3 * 7/3 is 21/3 or 7 in simplest form. The pole casts a shadow 7 feet tall. Plug in the numbers like this: 3/6 = 7/x. Cross multiply the values in order to get 3x = 42. now, you divide each side by 3 to isolate the "x". When you, you get x = 14. There. The height of the pole is 14 feet. The answer is C: 14 feet.
Answer:
37
-114
18
-8
Step-by-step explanation:
Just perform the operations eg 46 - 9 = 37.
Answer:
f(x)=4x^2 and g(x)=-8x^2 + 4x - 4
(f+g)(x) = -8x^2 + 4x - 4 + 4x^2 = -4x^2 + 4x - 4 = -4(x^2 -x + 1)
(f+g)(-3) = -4( -3^2 -(-3) + 1) = -4 x 13 = -52
Hope this helps!
