Answer:

x=\frac{\pm\sqrt{29} +1}{4}

Step-by-step explanation:

Quadratic Formula: x=\frac{-b \pm\sqrt{b^2-4ac} }{2a}

Step 1: Write quadratic equation

4x² - 2x = 7

Step 2: Solve for <em>x</em>

  1. Move everything to one side: 4x² - 2x - 7 = 0
  2. Define variables: a = 4, b = -2, c = -7
  3. Plug into quadratic formula: x=\frac{-(-2) \pm\sqrt{(-2)^2-4(4)(-7)} }{2(4)}
  4. Evaluate for <em>x</em>: x=\frac{\pm\sqrt{29} +1}{4}

Is an equation with an integer coefficient will always have an integer solution true or false?
eduard
An equation with an integer coefficient will always have an integer solution. Integers are whole numbers ( positive and negative and zero ). One example of equation:
4 x = 5  ( 4 is an integer coefficient )
x = 5 : 4 = 1.25 ( not an integer )
Answer:
This is false.

Find the values of x and y if
soldi70 [24.7K]

Answer:

see explanation

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, then

CA = NE , that is

4x + 3 = 11 ( subtract 3 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

----------------------------------------

AR = EW, that is

4y - 12 = 10 ( add 12 to both sides )

4y = 22 ( divide both sides by 4 )

y = 5.5

-------------------------------------------

NW = x + y = 2 + 5.5 = 7.5

CR = NW = 7.5

meaning you multiply (p-4) by (p+3)

Step-by-step explanation:

Product is the answer to a multiplication problem

Sum is the answer to an addition problem

p squared - p - 12 =

(p-4)(p+3)
