In a quadratic equation, the standard equation is represented as follows:

Ax^2 + Bx + C = 0

where A, B and C are constants and A should not have a zero value.

The values of A, B, and C would be as follows:

A = 1/2
B = -3
C = -2

Hope this answers the question. Have a nice day.

The drama club spent $35 on decorations and $8.50 per person on food for a cast party. The total cost of the food

jenyasd209 [6]

Answer:

Option C) 27 people

Step-by-step explanation:

Let

x ----> the number of people

we know that

The cost of decorations ($35) plus the number of people (x) multiplied by the cost per person on food ($8.50) must be equal to $264.50

so

The linear equation that represent this situation is

$35+8.50x=264.50$

solve for x

Subtract 35 both sides

$8.50x=264.50-35$

$8.50x=229.50$

Divide by 8.50 both sides

$x=229.50/8.50$

$x=27\ people$

the perimeter of a triangle is 49cm.One side is 7cm longer than another side and 5cm shorter than the third side find sides

pogonyaev

<em>P = a + b + c = 49 cm</em>

<em>a = b + 7 => b = a - 7</em>

<em>a = c - 5 => c = a + 5</em>

<em>_____________________</em>

<em>a + (a - 7) + (a + 5) = 49</em>

<em>3a = 49 + 7 - 5</em>

<em>3a = 51 </em>

<em>a = 17 cm</em>

<em>b = 17 - 7 = 10 cm</em>

<em>c = 17 + 5 = 22 cm</em>
