Answer:

The missing number is 4

Step-by-step explanation:

Given

21 x 39 x _____ x 19 divided by 12 = 5187

Required

Fill in the gap

Let the missing number be represented with y; So, the expression becomes

$\frac{21 * 39 * y * 19 }{12} = 5187$

Multiply both sides by 12

$12 * \frac{21 * 39 * y * 19 }{12} = 5187 * 12$

$21 * 39 * y * 19 = 62244$

Rearrange the expression on the left hand side

$21 * 39 * 19 * y = 62244$

$15561 * y = 62244$

Divide both sides by 15561

$\frac{15561 * y}{15561} = \frac{62244}{15561}$

$y = \frac{62244}{15561}$

$y = 4$

Hence, the missing number is 4

tatyana61 [14]

Answer:

Step-by-step explanation:

5.(a)

x²+6x-15=0

$x=\frac{-6\pm\sqrt{36+4*15}}{2*1}\\x=\frac{-6\pm\sqrt{36+60} }{2}\\x=\frac{-6\pm\sqrt{96} }{2}\\x=\frac{-6\pm4\sqrt{6} }{2}\\x=-3\pm2\sqrt{6}$

(b)

4x²-8x-1=0

$x=\frac{8\pm\sqrt{64+4*4}}{2*4}\\x=\frac{8\pm\sqrt{80}}{8}\\x=\frac{8\pm 4\sqrt{5} }{8}\\x=\frac{2\pm\sqrt{5}}{2}$
