Answer:
c = 10
Step-by-step explanation:
The pythagoras theorem :
a² + b² = c²
a = 6 and b = 8
6² + 8² = c²
36+64 = c²
100 = c²
c = √100
c= 10

Answer:
<h2>x = 9/17</h2>
Step-by-step explanation:
3(7x-1)=4x+6 distribute
21x - 3 = 4x + 6 combine similar terms
21x - 4x = 6 + 3 simplify
17x = 9
x = 9/17
The first one is 11 and -11 because when you square them they both get 121
The second one is -7 and -1
Answer:
g = 118°, h = 62°, k = 140°, m = 40°
Step-by-step explanation:
g = 118°
h = 180 - 118 = 62°
k = 140°
m = 180 - 140 = 40°
Answer:
Given below
Step-by-step explanation:
The algebraic identity is (a-b)^2
= a^2 + b^2 - 2ab
So it'll be,
(x-4)^2
= x^2 + (4)^2 - (2)(x)(4)
= x^2 -8x + 16
or x^2 +16 -8x
