Since the opposite operation of addition is subtraction you subtract. So you add 14 both sides and now z is by itself. finally just add 2 and 14 which is 16

Find the distance between the points (5, -6) and (-1, 3).

Answer:

$\sqrt{117}$

Step-by-step explanation:

Use the distance formula.

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(-1 - 5)^2 + (3 - (-6))^2}$

$d = \sqrt{(-6)^2 + 9^2}$

$d = \sqrt{36 + 81}$

$d = \sqrt{117}$

It is given that -7, h, k, 20,... are the first 4 terms of an arithmetic progression.

dexar [7]

Answer:

the answer should be B

Step-by-step explanation:

the first part is basically finding the difference between the terms, as we know that d=T2-T1

so by comparing the T2-T1 and T3-T2 we can find the difference with the two variables h and k

afterwards do the same with T4-T3 and T3-T2, comparing them and you will get another equation

now that you have two equations, you can do simultaneous equation to get the answers

hope i helped :D

Help please!!!!!! 12-13 8th grade math!!!

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x° = 180°

x° = 180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN = 60° + 90° = 150°
