Answer:

a) 0,4,8,12,16,20

b)In each number add 4 for example 16+4 = 20, 20 + 4 =24 .

44,41,38,35,32

in this sequence take away 3 for example 35 - 3 = 32, 32-3=29

32, 29, 26, 23, 20

20 is the number that is in both sequence.

Help me with these 2 questions please

Margaret [11]

Answer:

1st one= B 25 cents

2nd one= D 2 miles

Step-by-step explanation:

8x3=24

6/24=25

= 25 cents

1.6 km= 1 mile

so 1/2 of a mile =

0.8 km

1/4 of an hour = 15 minutes

0.8km= 15 minutes

15x3= 45 minutes

0.8km x 3= 2.4km

2.4km = 2 miles

hope it helps hunney xx

For this case we must find the solution of the following quadratic equation:

$x ^ 2 + 5x + 7 = 0$

Where:

$a = 1\\b = 5\\c = 7$

Then, the solution is given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting the values:

$x = \frac {-5 \pm \sqrt {5 ^ 2-4 (1) (7)}} {2 (1)}\\x = \frac {-5 \pm \sqrt {25-28}} {2}\\x = \frac {-5 \pm \sqrt {-3}} {2}$

By definition we have: $i ^ 2 = -1$

$x = \frac {-5 \pm \sqrt {3i ^ 2}} {2}\\x = \frac {-5 \pm i \sqrt {3}} {2}$

Thus, we have two complex roots.

Answer:

The equation has no real roots.
