I think that x may equal to -3. Because the sum of a triangle is always 180. 55+54=109 and 180-109=71 and -3+74=71

Instead of = 360 it should be 180

X+183=180
X= -3

X is -3 that does not make the angle negative 3X -3+74 which is 71 for the angle but it is equal to -3
If you add 55+54+71= 180

Each side of the smaller square in the figure below is n inches long, and each side of the larger square is p inches longer than

lana66690 [7]

Answer:

2np + p²

Step-by-step explanation:

The general formula for the area of a square is A = s², where s = the length of one side of the square. In the case of the smaller square the area would be: n x n = n². Since the side of the larger square is 'p' inches longer, the length of one side is 'n + p'. To find the area of the larger square, we have to take the length x length or (n +p)².

Using FOIL (forward, outside, inside, last):

(n + p)(n+p) = n² + 2np + p²

Since the area of the first triangle is n², we can subtract this amount from the area of the larger square to find out how many square inches greater the larger square area is.

n² + 2np + p² - n² = 2np + p²

Write the formula for the volume of a square prism, V = s-h, in terms of h. Then find the height h of a square prism with volume

vodomira [7]

Answer:

$h = \frac{3V}{s^2}$

height (h) = 5 cm

Step-by-step explanation:

Volume of prism in terms of h (height):

$V = \frac{1}{3}s^2h$

$V = \frac{s^2h}{3}$

Multiply both sides by 3

$V*3 = \frac{s^2h}{3}*3$

$3V = s^2h$

Divide both sides by s^2

$\frac{3V}{s^2} = \frac{s^2h}{s^2}$

$\frac{3V}{s^2} = h$

$h = \frac{3V}{s^2}$

Find height (h) given V = 60 cm³ and side length (s) = 6 cm. Plug the values into the formula above:

$h = \frac{3(60)}{6^2}$

$h = \frac{180}{36}$

$h = 5$

Height = 5 cm

Evaluate 4 2/3-(-1 4/5)

Blababa [14]

Find a common denominator by multiplying the two different denominators by each other to get 15. 2/3 then becomes 10/15 and 4/5 becomes 12/15.

You now have 4 and 10/15 minus negative 1 and 12/15. Subtracting a negative number results in addition, so it's 4 and 10/15 PLUS 1 and 12/15. You get 5 and 22/15, which becomes 6 and 7/15.

The answer is C.
