The answer is A is equal to 2
Answer:
Step-by-step explanation:
Rewrite this quadratic equation in standard form: 2n^2 + 3n + 54 = 0. Identify the coefficients of the n terms: they are 2, 3, 54.
Find the discriminant b^2 - 4ac: It is 3^2 - 4(2)(54), or -423. The negative sign tells us that this quadratic has two unequal, complex roots, which are:
-(3) ± i√423 -3 ± i√423
n = ------------------- = ------------------
2(2) 4
Answer:
48
Step-by-step explanation:
Here, the sides are in proportion.
⇒ 
⇒ 
⇒ k = 24 × 2
⇒ k = 48
Let x represent the number of DVDs and y represents the number of CDs.
DVDs are sold for 8$ and CDs are sold for 6$.
If you have 50$ to buy gift cards then the following inequality should be satisfied:
8*x+6*y<50
Answer:
The length of side <em>b</em> is 9.
Step-by-step explanation:
Triangles are similar if they have the same shape, but can be different sizes.
When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. We know that the triangle
is similar to the triangle
. Therefore the following relation must be true:

We know that side
is equal to 8, side
is equal to <em>b, </em>side
is equal to
, and side
is equal to 3.
Substituting these values into the above relation and solving for <em>b</em> we get that:
