General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

3p² - 7p - 1 = 0

Step 2: Identify Variables

a = 3

b = -7

c = -1

Step 3: Find roots

x = 7 + √61 ÷ 6

Step-by-step explanation:

3p² - 7p - 1 = 0 is a given equation

3p² - 7p - 1 = 0

Here,

a = 3

b = - 7

c = - 1

Now, Discriminant

D = b² - 4ac

= (- 7)² - 4 (3)(- 1)

= 49 + 12

D = 61 > 0

So, Quadratic Equation

ax² + bx + c = 0

x = - b ± √b² - 4ac ÷ 2a

x = - (- 7) ± √(- 7)² - 4 (3)(- 1) ÷ 2(3)

x = 7 ± √61 ÷ 6

x = 7 ± √61 ÷ 6

x = 7 + √61 ÷ 6 or x = 7 - √61 ÷ 6

∴ Not real Value

Thus, The real value of x is 7 + √61 ÷ 6

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
