Move all terms to one side

4x^2 - 3 - 11x = 0

Split the second term in 4x^2 - 3 - 11x into two terms

4x^2 + x - 12x - 3 = 0

Factor out common terms in the first two terms, then in the last two terms

x(4x + 1) -3(4x + 1) = 0

Factor out the common term 4x + 1

(4x + 1)(x - 3) = 0

Solve for x

<u>x = -1/4, 3</u>

<u>Answer: C. {-1/4, 3}</u>

Answer:

x = 5.75

Step-by-step explanation:

4^(x+7) = 8^(2x-3)

But; 4^(x+7) = 2^2(x+7)

8^(2x-3) = 2^3(2x-3)

2^2(x+7) = 2^3(2x-3)

Since the bases are the same;

2(x+7) = 3(2x-3)

2x + 14 = 6x -9

14 + 9 = 6x - 2x

23 = 4x

x = 23/4

<u>x = 5.75</u>

At the same time a 12 foot adult elephant cast a 4.8 foot shadow a baby elephant casts a 2 foot shadow how tall is the baby elep
Vsevolod [243]
Set up a proportion here as the height over the shadow of the adult = to the height over the shadow of the baby. so you have 12/4.8 = height/2. cross multiply to get 12*2=4.8 times height, which is 24 = 4.8*height. divide both sides by 4.8 to get height = 5 feet
