Answer:

x = 13

Step-by-step explanation:

a^{2} +b^2 = c^2\\12^2 + 5^2 = c^2\\144 + 25 = c^2\\169 = c^2\\

Take the square root of both sides

\sqrt{169} = \sqrt{c^2} \\13 = c

sheila has to pack 128 baskets of apples. she has packed 1/4 of the basket. How many baskets are left for her to pack
Natalka [10]
To answer this we will DIVIDE the amount of baskets by 4 (since it is 1/4) to see how many she has ALREADY packed, and ho many she has left. Lets do it:-

128 ÷ 4 = 32 

CHECK OUR WORK:-

32 × 4 = 128.

So, she has done 32 baskets. lets see how many more she needs to pack:-

128 - 32 = 96.

So, Shelia has 96 baskets LEFT to pack,

Hope I helped ya!!

Please help on this pythagorean question, find x.
svp [43]

Answer:

x = 4

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

(x + 3)² + (4(x + 2))² = 25² ← expand parenthesis on left side

x² + 6x + 9 + 16(x+ 2)² = 625

x² + 6x + 9 + 16(x² + 4x + 4) = 625

x² + 6x + 9 + 16x² + 64x + 64 = 625 ← simplify left side

17x² + 70x + 73 = 625 ( subtract 625 from both sides )

17x² + 70x - 552 = 0 ← in standard form

with a = 17, b = 70, c = - 552

Using the quadratic formula to solve for x

x = ( - 70 ± \sqrt{70^2-(4(17)(-552)} ) / 34

  = ( - 70 ± \sqrt{4900+37536} ) / 34

  = - 70 ± \sqrt{42436} ) / 34

  = - 70 ± 206 ) / 34

x = \frac{-70-206}{34} = - 8.1176....

or x = \frac{-70+206}{34} = 4

However, x > 0 ⇒ x = 4

Hence

x + 3 = 4 + 3 = 7 and

4(4 + 2) = 24

The triangle is a 7- 24- 25 right triangle

Harman [31]
In this case, you simply count how many cubes are in the length, width, and height and multiply them together. In the example problem, the answer is 75 blocks because the dimensions are 5 x 5 x 3.
