= 3.35
$3.35 per sandwitch
Answer:
(x - 3)(x + 7)
Step-by-step explanation:
x^2 + 4x - 21
=> x^2 + 7x - 3x - 21
=> x(x + 7) -3(x + 7)
=> (x + 7)(x - 3)
So the graph shows a division problem. the green parts represent 1/4 of the rectangle. and that 1/4 has been cut into 5 parts. so i think it would be d.
<u>To find the constant of proportionality:</u>
⇒ must define constant of proportionality
⇒ <em>Constant of Proportionality: ratio of two proportional values at a </em>
constant value
⇒ (in this case) two proportional values are x and y
<u>The ratio between x and y is equal to</u>

<u>Answer:</u> <u>55</u> or <u>Choice 1</u>
<u></u>
