Mathematics

LuckyWell [14K]3 years ago
6 0

Answer:

k = 10

Step-by-step explanation:

There are 180 degrees in a straight line, so ZYX must be 85 degrees. There are also 180 degrees in a triangle, so YZX + ZXY = 115.


4k + 5 + 6k + 10 = 115

10k + 15 = 115

10k = 100

k = 10

Answer:

a) x = 13

b) x = 7

Step-by-step explanation:

A) Since they have the same base of 2 so

x + 4 + (-5) = 12

          x - 1 = 12

               x = 13

b) Since they have the same base of -3 so

8 + x + 4 = 19

   x + 12 = 19

          x = 7

Help please explain in detail
yaroslaw [1]

Answer:

1. (n + 3)(5n + 8)

2. (x - 4)(7x - 4)

3. (k + 8)(7k + 1)

Step-by-step explanation:

1. We have to factorize 5n² + 23n + 24.

Now, 5n² + 23n + 24

= 5n² + 15n + 8n + 24

= 5n (n + 3) + 8 (n + 3)

=(n + 3)(5n + 8) (Answer)

2. We have to factorize 7x² - 32x + 16

Now,  7x² - 32x + 16

= 7x² - 28x - 4x + 16

= 7x (x - 4) - 4 (x - 4)

= (x - 4)(7x - 4) (Answer)

3. We have to factorize 7k² + 57k + 8

Now, 7k² + 57k + 8

= 7k² + 56k + k + 8

= 7k (k + 8) + 1 (k + 8)

= (k + 8)(7k + 1) (Answer)
