Which is a solution to (x – 3)(x + 9) = –27? x = –9 x = –3 x = 0 x = 6

2 answers:

8 0

Expand
x²+6x-27=-27
add 27 both sides
x²+6x=0
factor
x(x+6)=0
set to zero

x=0

x+6=0
x=-6

x=0 or -6

answer is 0 since -6 is not listed

First you would multiply x by x so x^2. next x*9 would be 9x then -3*x would be -3x last you would do -3*9 would be -27 then you would simplify that out

Oxana [17]

Answer:

32.43

Step-by-step explanation:

To get the standard divisor

We sum up the tickets sold

Applejack's = 66 tickets

Broncos = 769 tickets

Colts = 652 tickets

Deers = 556 tickets

The total prize amount = $63

Total tickets = 66 + 769 + 652 + 556 = 2043

Standard divisor = 2043/63

= 32.43

The standard divisor to two decimal places is 32.43

Answer:

The angle between the two sides of the right triangle is aproximately 31.003º.

Step-by-step explanation:

From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:

$\cos \alpha = \frac{6}{7}$
