Henry has two pixie sticks full of delicious sugar. Henry
Sholpan [36]

Answer:

14.67 gram

Step-by-step explanation:

Henry has two pixie sticks full of delicious sugar.

Now, each pixie stick contains 22 grams of sugary goodness, then in two sticks, there will be (22 × 2) = 44 grams of sugar.

Now, Henry shares two pixie sticks among two friends and himself in equal proportion.  

Therefore, each of his friends will get \frac{44}{3} = 14.67 (Round to the nearest tenth) gram of sugary goodness. (Answer)

Simplify (4x^2-7x+14)(3x+5x^2-6)<br> Please show work
tatiyna

Answer:

-23x^3+20x^4+25x^2+84x-84

Step-by-step explanation:

1 Expand by distributing sum groups.

4x^2(3x+5x^2-6)-7x(3x+5x^2-6)+14(3x+5x^2-6)

2 Expand by distributing terms.

12x^3+20x^4-24x^2-7x(3x+5x^2-6)+14(3x+5x^2-6)

3 Expand by distributing terms.

12x^3+20x^4-24x^2-(21x^2+35x^3-42x)+14(3x+5x^2-6)

4 Expand by distributing terms.

12x^3+20x^4-24x^2-(21x^2+35x^3-42x)+42x+70x^2-84

5 Remove parentheses.

12x^3+20x^4-24x^2-21x^2-35x^3+42x+42x+70x^2-84

6 Collect like terms.

(12x^3-35x^3)+20x^4+(-24x^2-21x^2+70x^2)+(42x+42x)-84

7 Simplify.

-23x^3+20x^4+25x^2+84x-84

WILL MARK BRAINIEST, QUESTION IS HARD, Ann works for a city’s parks and recreation department. She is looking for some commercia
MrRa [10]

Answer:

x =320

Step-by-step explanation:

Given

x^2 + 200x = 166400

Required

Find x

We have:

x^2 + 200x = 166400

Rewrite as:

x^2 + 200x - 166400 = 0

Expand

x^2 + 520x - 320x - 166400 = 0

Factorize

x(x + 520) - 320(x + 520)= 0

Factor out x + 520

(x - 320) (x + 520)= 0

Split

x - 320 = 0\ or\ x + 520= 0

Solve

x = 320\ or\ x =- 520

Side length must be positive;

So:

x = 320

3 On a coordinate grid, the location of a lighthouse is at L, and the location of a buoy is at B. At noon, a ship is at the midp
Zarrin [17]

Answer:

(\frac{1}{2}, 2)

Step-by-step explanation:

Using the midpoint formula, M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}), we can find the coordinates that represents the position of the ship at noon.

Let L(-4, 7) = (x_1, y_1) (given on the coordinate plane)

B(5, -3) = (x_2, y_2) (given also)

Plug in the values into the formula and solve as follows:

M(\frac{-4 + 5}{2}, \frac{7 +(-3)}{2})

M(\frac{1}{2}, \frac{7 - 3}{2})

M(\frac{1}{2}, \frac{4}{2})

M(\frac{1}{2}, 2)

Position of the ship at noon is best represented at (\frac{1}{2}, 2)
