Answer:
(x,y) (-3,4)
Step-by-step explanation:
Answer:
n = -8
Step-by-step explanation:
Given the expression
(-2y-3) + (-6y-5) = (ny -8),
Expanding the LHS
-2y-3 - 6y -5 = ny - 8
-2y-6y-3-5 = ny - 8
-8y - 8 = ny - 8
Compare both sides
-8y = ny
-8 = n
Swap
n = -8
Hence the value of n is -8
A = 1/5
d = T2-T1
d = 1/10 - 1/5
d = 1/10 - 2/10
d = - 1/10
T4 = 1/5 + 3(-1/10)
= 1/5 - 3/10
= 2/10 - 3/10
= - 1/10
Sum of all the angles in a triangle = 180°
(2x + 5) + (6x - 10) + (x + 5) = 180
2x + 5 + 6x - 10 + x + 5 = 180
Combine like terms:
9x = 180
Divide by 9:
x = 20
Answer: x = 20°
