2x2 − 12x + 21. Axis of symmetry. 2.
Answer:
x = 130
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360
140 + x + 56+ 34 = 360
Combine like terms
230 +x = 360
Subtract 230 from each side
230+x-230 = 360-230
x =130
60 + 90
GCF = 30
(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way
The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.
Answer:
3 tothe one it is the answer
One way is brute force or experiment
20*10=200
20*100=2000
20*50=1000, that is the first 4 digit number
now add 5
1005
the answer is 1005
