Order of operation? 5p^2 = h when p =2 and h = 8

Naddika [18.5K]

Given: p=2, h=8

5p^2=h

5(2)^2=8 ------- substitution here

5(4)=8

20 doesn't equal 8

I did exponents first because it comes before multiplication in the order of opertions.

Solve for x in the equation x^2- 10x+ 25=35

DIA [1.3K]

Answer:

Step-by-step explanation:

x² - 10x + 25 = 35

Move 35 to the left side of the equation

That's

x² - 10x + 25 - 35 = 0

x ² - 10x - 10 = 0

Using the quadratic formula solve the equation

That's

From the question

a = 1 , b = - 10 , c = - 10

Substitute the values into the above formula and solve

That's

$x = \frac{ - - 10\pm \sqrt{( { - 10})^{2} - 4(1)( - 10) } }{2(1)} \\ = \frac{10\pm \sqrt{100 + 40} }{2} \\ = \frac{10\pm \sqrt{140} }{2} \\ = \frac{10\pm2 \sqrt{35} }{2} \\ = \frac{10}{2} \pm \frac{2 \sqrt{35} }{2} \\ = 5\pm \sqrt{35}$

We have the final answer as

Hope this helps you
