If the perimeter is 26, and the width is 4, then add 4 twice, to get 8. Then subtract 8 from 26 to then get 18, you have two lengths, so divide 18 by 2. Your answer is 9.
To check add 4+4+9+9 = 26.
hope it helped! :)
12j^2k - 36j^6k^6 + 12j^2 = 12j^2(k - 3j^4k^6 + 1)
Answer:
FIRST. Multiply both sides of the bottom equation by 2
Step-by-step explanation:
12x - y = 26
×2 ×2
24x - 2y = 52
-2 is opposite to 2
M∠3 + m∠4 = 180° ( RIGHT)
m∠2 + m∠4 + m∠6 = 180° ( RIGHT)
m∠2 + m∠4 = m∠5 ( RIGHT)
m∠1 + m∠2 = 90° (WRONG)
m∠4 + m∠6 = m∠2 (WRONG)
m∠2 + m∠6 = m∠5 (WRONG)
Answer:
I think it's A, because all triangles have 3 vertices.
