To find it it is
ax^2+bx+c
if the first term (a) is 1 then c=b/2
b=-1/4
(-1/4)/2=-1/4 times 1/2=-1/8

k=-1/8

Choose the expression that completes the equation.

worty [1.4K]

The correct answer would be 3(7+1) because 7+1=8 and 8 times 3 equals 24. 24 divided by six is 4 plus 20 would also be 24.

Which of the following expressions has a value of 26.48?

gulaghasi [49]

Answer:

$26.48=\dfrac{662}{25}$

Step-by-step explanation:

The given expression is 26.48. We need to write the equivalent expression for it. There are two numbers after decimal. It means that we can divide 2648 by 100 i.e.

$26.48=\dfrac{2648}{100}$

We know that, 2648 = 662 × 4 and 100 = 25 × 4

$\dfrac{2648}{100}=\dfrac{662\times 4}{25\times 4}\\\\=\dfrac{662}{25}$

Hence, $26.48=\dfrac{662}{25}$ is the equivalent expression.
