A portion of the Quadratic Formula proof is shown. Fill in the missing reason. Statements Reasons ax2 + bx + c = 0 Given ax2 + b

x = −c Subtract c from both sides of the equation x squared plus b over a times x equals negative c over a Divide both sides of the equation by a x squared plus b over a times x plus the quantity b over 2 times a squared equals negative c over a plus the quantity b over 2 times a squared Complete the square and add the quantity b over 2 times a squared to both sides x squared plus b over a times x plus the quantity b over 2 times a squared equals negative c over a plus b squared over 4 times a squared Square the quantity b over 2 times a on the right side of the equation x squared plus b over a times x plus the quantity b over 2 times a end quantity squared equals negative 4 times a times c over 4 times a squared plus b squared over 4 times a squared Find a common denominator on the right side of the equation x squared plus b over a times x plus the quantity b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Add the fractions together on the right side of the equation quantity x plus b over 2 times a end quantity squared equals b squared minus 4 times a times c all over 4 times a squared ? Rewrite the perfect square trinomial as a binomial squared on the left side of the equation Take the square root of both sides of the equation Multiply both sides of the equation by 2 Square the left side of the equation

Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:

  • 2 + 3 = 5
  • 4 - 1 = 3
  • 2 × 2 = 4
  • 4 ÷ 2 = 2
  • 2² + 1 = 5
  • (1 + 2) + (2 × 1) = 5
  • (2 + 3) - 4 = 1
  • (2 + 2)² ÷ 4 = 4
  • (2 ÷ 4)² × 4 = 1
  • (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

<h3>What is a mathematical expression? </h3>

A mathematical expression is a sequence of characters that are intended to express a general relationship between the terms expressed in the formula.

Mathematical expressions generally have symbols like:

  • Add +
  • Subtraction -
  • Multiplication ×
  • Division ÷
  • Exponent x^{x}
  • Equal =
  • Parentheses ()

According to the above, some examples of mathematical expressions are:

  • 2 + 3 = 5
  • 4 - 1 = 3
  • 2 × 2 = 4
  • 4 ÷ 2 = 2
  • 2² + 1 = 5
  • (1 + 2) + (2 × 1) = 5
  • (2 + 3) - 4 = 1
  • (2 + 2)² ÷ 4 = 4
  • (2 ÷ 4)² × 4 = 1
  • (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

Montano1993 [528]
Hi there,

There are 16 members in a math club such as 2 girls and 14 boys in a math club.

The ratio would be:

1:7

Divide both terms by 2.
2 ÷ 2 = 1
14 ÷ 2 = 7

Therefore:
2 : 14 = 1 : 7

slavikrds [6]
A=pi(radius^2)
630/3.14=200.64
radius=14.16 feet
C=2(pi)(radius)
=3.14(2)(14.16)
=6.28(14.16)
C=88.92
88.92<100
Yes! He has enough fencing to enclose the circular area.
