Answer:
SAS
Step-by-step explanation:
The triangles are compared with 2 sides and 1 angle. So, it is SAS
Answer:5
Step-by-step explanation:
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
Answer:
6468
Step-by-step explanation:
6468 is equivalent to 1617
because 64 x 17 = 1088 and
68 x 16 = 1088.
