Step-by-step explanation:

If you need an explanation tell me in comments <3

Answer 2

(x + 3)² = 25 and x² + 6x + 9 = 25 are equivalent to x² + 6x = 16.

What is a quadratic equation?

A quadratic equation is an algebraic equation of 2nd degree usually in the form of ax² + bx + c = 0.

Given,

x² + 6x = 16

⇒ x² + 2 × 3 × x = 16

⇒ x² + 2 × 3 × x +9 = 16 + 9

⇒ (x)² + 2 × 3 × x +9 = 25

⇒ (x + 3)² = 25

⇒ x² + 6x + 9 = 25

Hence, (x + 3)² = 25 and x² + 6x + 9 = 25 are equivalent to x² + 6x = 16.

Please help ASP!!!! A= positive, B=Negative, C=Zero​

Answers

Answer:

B. Negative

Step-by-step explanation:

So first, we want to locate the variable.

y (x/y) = (y/1) (x/y)

           = (xy/y)

           = x

The y/y cancels out and now we know we need to find the sign of x. Because x is to the left of 0, it's negative. Anything to the left decreases and anything to the left of 0 is (-).

Answer:

Option A. x = –5 ± √133 / –6

Step-by-step explanation:

0 = –3x² + 5x + 9

From the above equation the following data were obtained:

Coefficient of x² (a) = –3

Coefficient of x (b) = 5

Constant (c) = 9

Using formula method, the solution to the equation can be obtained as follow:

x = –b ± √(b² – 4ac) / 2a

a = –3

b = 5

c = 9

x = –5 ± √(5² – 4 × –3 × 9) / 2 × –3

x = –5 ± √(25 + 108) / –6

x = –5 ± √133 / –6

Thus, option A gives the correct answer to the question.

Answer:

I’m not 100% sure but I think 120°.

Step-by-step explanation:

This is because, angles on a straight line add up to 180°. Because there is 60 degrees on one side of line B, this means the other section is 120° (120°+60°=180°) The angle labelled (3x) is alternate to the angle of 120°. Alternate angles are always equal, meaning that 3x is equal to 120°.

I hope this is right.
