Answer:

The correct answer is option B.

Step-by-step explanation:

Given quadratic equation : y^2-12y+32

Using middle term splitting theorem:

=y^2-12y+32

=y^2-8y-4y+32

=y(y-8)-4(y-8)

=(y-8)(y-4)

y = 8, 4

The factors of given quadratic equation is (y-8)(y-4).

Express x in terms of a and b: b−7x=a−b
pav-90 [236]
B - 7x = a - b
Subtract b from both sides.

-7x = a - 2b
Divide both sides by -7.

x = \frac{-a + 2b}{7}

-3.75+2(-4x+6.1)-3.25
Pani-rosa [81]

The value of x is 0.65

<u>Step-by-step explanation:</u>

This solution is given by solving the given problem using BODMAS rule.

This means that the steps to be followed to find the solution should be in the order of BODMAS rule.

B- Bracket, O- of, D- Division, M- Multiplication, A- Addition, S- Subtraction.

This rule states that the 1st operation must be done for Brackets.

⇒ -3.75+2(-4x+6.1)-3.25 = 0

⇒ -3.75 -8x + 12.2 -3.25 = 0

The addition operation should be performed next and then followed by subtraction.

⇒ -8x -7+ 12.2 = 0

<u>To find the value of x :</u>

Keeping the x term alone on one side and moving the constants on other side,

⇒ -8x = -12.2 + 7

⇒ -8x = -5.2

⇒ x = 5.2/8

⇒ x = 0.65
