<h2>Greetings!</h2>

Answer:

€16.40

Step-by-step explanation:

First, we need to divide £12.30 by 3 to find out how many groups of 3 there is:

12.3 ÷ 3 = 4.1

Now we can multiply this by 4 to find the euro equivalent:

4.1 * 4 = 16.4

So £12.30 is €16.40

Find the value of the discriminant for all the equations. 1.5q2 +2q–3=0 2.3u2 -4u+1=0 3.7s2 +9s–4=0 4.6w2 –8w+5=0 5.5p2 +7p–3=0
kicyunya [14]

Answer:

Case 1: a = 1.5, b = 2, c = -3

D = 22

Case 2: a = 2.3, b = -4, c = 1

D = 6.8

Case 3: a = 3.7, b = 9, c = -4

D = 140.2

Case 4: a = 4.6, b = -8, c = 5

D = -28

Case 5: a = 5.5, b = 7, c = -3

D = 115

Case 6: a = 6.9, b = -5, c = 2

D = -30.2

Case 7: a = 7.2, b = 6, c = -4

D = 151.2

Case 8: a = 8.3, b = -3, c = 4

D = -123.8

Case 9: a = 9.9, b = 4, c = -7

D = 293.2

Case 10: a = 10.4, b = 8, c = -5

D = 272

Step-by-step explanation:

For all second order polynomial, the discriminant is equal to:

D = b^{2}-4\cdot a \cdot c

Case 1: a = 1.5, b = 2, c = -3

D = 22

Case 2: a = 2.3, b = -4, c = 1

D = 6.8

Case 3: a = 3.7, b = 9, c = -4

D = 140.2

Case 4: a = 4.6, b = -8, c = 5

D = -28

Case 5: a = 5.5, b = 7, c = -3

D = 115

Case 6: a = 6.9, b = -5, c = 2

D = -30.2

Case 7: a = 7.2, b = 6, c = -4

D = 151.2

Case 8: a = 8.3, b = -3, c = 4

D = -123.8

Case 9: a = 9.9, b = 4, c = -7

D = 293.2

Case 10: a = 10.4, b = 8, c = -5

D = 272

Drag expressions into order to show a way to find 3 × 56.
lina2011 [118]
As we could "drag" these together, we could then do it the easy way.

  56
+56
+56
-------
168
------------------------

Or we could also do the following:

56*3:

6*3= 18.

Carry the one. 

5*3 = 15+1 (which was carried). = 16

(16+8) = 168
