Solve for q. √3q + 2 = √5

34kurt

Answer:

$q = 0.0186$

Step-by-step explanation:

To solve for q, we initially place everything with the term q to one side of the equality, and everything without the term q to the other side of the equality.

$\sqrt{3q} + 2 = \sqrt{5}$

$\sqrt{3q} = \sqrt{5} - 2$

We find the square of both sides of the equation. So

$(\sqrt{3q})^{2} = (\sqrt{5} - 2)^{2}$

$3q = 0.0557$

$q = \frac{0.0557}{3}$

$q = 0.0186$

Find the value of c that makes each trinomial a perfect square. Then write the trinomial as a perfect square.

musickatia [10]

Answer:

d. c = 100; (x – 10)²

Step-by-step explanation:

Note that (x+a)²=x²+2ax+a².

In our case, 2a=-20, so 'a' must be -10.

Since c=a², and a=-10, c=(-10²)=100.

Since a=-10, the perfect square is (x – 10)²

Jason wrote this expression to describe the total amount he will spend on a magazine and a book.

kati45 [8]

The 11 may represent the price of the magazine if all the magazines at a certain store are $11. Then the s may represent the price of a book because all the books at a bookstore are different prices.

Hope this helps
