Answer:
14
Step-by-step explanation:
(I go to a french school, so excuse my terminology, which might not always be correct)
The angle we can see, in GHI, is equal to 121°. JKL has an identical angle, meaning JKL is an enlargement (probably the wrong term, I apologise) of GHI. This means we can use the length of it's sides to find KL.
GH and GI are both multiplied by two (GH = 4 becomes JK = 8, GI = 5 becomes JL = 10) meaning you must multiply HI by 2 to find KL.
2*7 = 14
KL = 14
Answer:
the answer to - 2/5 -4/5 + - 9/10 is -2.1
B: 2;3
Step-by-step explanation:
GCF(greatest common factor) of 8 and 12 = 4
8/4=2 and 12/4=3
Answer:
See below.
Step-by-step ,explanation:
2^13 – 2^10 – 2^9
Take out the GCF, 2^9 :
= 2^9 (2^4 - 2 - 1)
= 2^9(16 - 3)
= 13 * 2^9.
So it must be divisible by 13.
