Answer 2

The value of x for the given quadratic equation is (19+[tex]\sqrt{1261}[/tex])/50,

(19-[tex]\sqrt{1261}[/tex])/50.

What is a quadratic equation?

It is in the form of a[tex]x^{2} +bx+c[/tex]. It is simply an equation and we have to solve for x.

How to solve a quadratic equation?

If we solve the given equation we will be able to get the following equation

[tex]25x^{2} -19x-9=0[/tex]

x=(-b+-[tex]\sqrt{b^{2}-4ac }[/tex])/2a

when we put b=19 a =25 c =-9

we will get x=[tex](19+\sqrt{1261} )/50 , (19-\sqrt{1261} )/50[/tex].

Answer:

B. First term = 5, Common difference = -3

Step-by-step explanation:

The first term is f(1) = 8 - 3(1) = 8 - 3 = 5.

The common difference is the coefficient of  n.  Another way to see this is to compute the second term, f(2) = 8 - 3(2) = 8 - 6 = 2.  The second term is 3 less than the first.  The common difference is -3.

The sequence goes 5, 2, -1, -4, ...

Step-by-step explanation:

The diagonals of a rhombus are at right angles to each other, then

∠ 1 = ∠ 2 = ∠ 3 = 90° so

10x = 90 ( divide both sides by 10 )

x = 9

x + y = 90

9 + y = 90 ( subtract 9 from both sides )

y = 81

9z = 90 ( divide both sides by 9 )

z = 10

What is an equation?

The term "equation" refers to a pair of algebraic expressions with the same value and the sign "=" in between.

We have an equation,

221 = x + 68

x = 221 - 68

x = 153

In 153,

1 is in place of hundred 100, 5 is in the place of 10 so, 50.

Therefore, x = 53 is the amount that needs to be to balance the scale.
