Answer:

h = 2A/b

Step-by-step explanation:

The given area triangle is denoted by:

A=1/2bh

By solving for "h", we're simply asked to make "h" the subject of the formula, that is putting "h" on one side of the equation and all other variable/values on the other side of the equation.

By doing this, we move other variables presently on the right side with "h" and the left hand side of the equation takes them all except "h", then we have:

2A/b = h.

Which two values of x are roots of the polynomial below? 5x2 - 5x+1

Natalija [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$5 {x}^{2} - 5x + 1 = 0$

$(x - \frac{5 + \sqrt{5} }{10} )(x - \frac{5 - \sqrt{5} }{10} ) = 0 \\$

Thus :

$x = \frac{5 + \sqrt{5} }{10} \\$

$x = \frac{5 - \sqrt{5} }{10} \\$

2. Y - 3 = X + 2 2X - 1 = Y Show your work

chubhunter [2.5K]

Y - 3 = X + 2 ...............….... (1)
2X - 1 = Y ........................... (2)

From (2),
2X - 1 = Y

Y = 2X - 1

Sub (2) into (1),
(2X-1) - 3 = X + 2

2X - 1 - 3 = X + 2

2X - X = 2 + 1 + 3

X = 6

Sub x=6 into (1),
Y = 2(6) - 1

Y = 12 - 1

Y = 11

How do I get the answer to this step by step?

AURORKA [14]

Answer:

Step-by-step explanation:

The exterior angle is 151 degrees. The theorem states that the sum of its 2 remote interior angles, 5x+3 and 9x-20, will add up to this exterior angle. Therefore,

5x+3+9x-20 = 151 and

14x - 17 = 151 and

14x = 151 + 17

14x = 168 so

x = 12

If you want to find out the measure of each of these angles, just plug in 12 for x and do the math:

5(12) + 3 = 63 and

9(12) - 20 = 88 and

88 + 63 = 151 as it should.
