Answer:
A. Scalene
E. Obtuse
Step-by-step explanation:
Obtuse are angles that are greater than 90°
Scalene is not congruent sides.
Because the factors of 33 are 11 and 3
31 doesn't have a factor of 11 or 3 so it is simplest form
also, 31 is prime so it can't be factored
Answer:
(2, -2)
Step-by-step explanation:
Given the equation
x - y = 4 ... 1
6x+y = 10 ...2
Add both expressions
x+6x = 4 + 10
7x = 14
x = 14/7
x = 2
Substitute x = 2 into equation 1;
From 1;
x - y = 4
2 - y = 4
y = 2-4
y = -2
Hence the solution to the system of equation is (2, -2)
