**Answer:**

6 AND 12

**Step-by-step explanation:**

3 x 2 = 6

3 x 4 = 12

The amount of money **Kyle **paid is **$25. **

<h3>Determine the price of nachos and chocolates </h3>

Two **simultaneous equations** can be derived from the question:

3n + 3c = $45 **equation 1**

n = 2c **equation 2**

Where:

- n = price of
**nachos ** - c = price of
**chocolate **

In order to determine the price of **chocolates, **please substitute for n in **equation 1. **

3(2c) + 3c = $45

6c + 3c = $45

9c = $45

c = $45/9 = $5

In order to determine the price of **nachos, **please substitute for c in **equation 2: **

n = 2($5)

n = $10

<h3>Amount Kyle paid </h3>

2($10) + $5

$20 + $5

= **$25**

X^2/2 = 7x

x^2 = 14x

x^2 - 14x = 0

A quadratic equation is of the form ax^2 + bx + c

Therefore, in 3x^2 + 5x + 7, c = 7

**Answer****:**

perimeter = 52

**Step-by-step explanation:**

side of square = 2x + 1

- so first lets find the perimeter of square

p = 4 × s (side)

p = 4(2x +1)............. from the given

p = 8x + 4...... we will come back for this equation

side of trianles = 2x,2x,3x + 10

- second lets find the perimeter of triangle

p = s + s + s ( all the three sides)

p = 2x + 2x + 3x + 10

p = 7x + 10........we got another equation we will use it later

- The question says the perimeter of square and the perimeter of triangle are equal so
- 8x + 4(the perimeter of square we solved before) = 7x + 10(the perimeter of triangle we solved before)

8x + 4 = 7x + 10

8x - 7x = 10 - 4

x = 6 ... now lets substitute x

8x + 4

8 × 6 +4

48 + 4

52

the same thing will happen if we substitute for the perimeter of triangle too.
