Answer:
16
Step-by-step explanation:
To solve a quadratic equation by using the completing the square method, the coefficient of the square term i.e x² must be one (1).
Therefore, we would have to first make the coefficient of x² to be equal to 1.
4x² + 24x + 8 = 32
We would simplify the equation;
4x² + 24x = 32 - 8
4x² + 24x = 24
Divide all through by 4;
x² + 8x = 24
The value to be added = (8/2)² = 4² = 16
x² + 8x + 16 = 8 + 16
x² + 4x + 4x + 16 = 24
x(x + 4) + 4(x + 4) = 24
(x + 4)² = 24
Taking the square root of both sides;
x + 4 = ± 4.9
x = -4 ± 4.9
x = -4 + 4.9 = 0.9
or
x = -4 - 4.9 = - 8.9
<em>Therefore, 16 must be added to solve the quadratic equation by completing the square method. </em>
Answer:
T = 1yrs and 8month
Step-by-step explanation:
S.I = $97.3O
S.I = PTR/100
$<u>97.30</u> = <u>$1200 × 4.5 × T</u>
1 100
Cross multiply
$5400T = $9730
divide both sides by$5400
T = 1.8yrs
Answer:
16 bags
Step-by-step explanation:
To find this, we <em>divide 2 over 1/8</em>, to see how many <em>units of 1/8 fits into that of 2</em>.
can be rewritten as <em>2*8</em>. 2*8 = 16 bags.
