Answer:
31²
Step-by-step explanation:
To find the answer first multiply 9 by 15 to get 135. Now multiply 8 by 13 to get 104. Now subtract 104 from 135 to get 31² as your answer.
2x-3y=13
x+2y=-4
First times the second problum by 2.
2x-3y=13
2(x+2y=-4)
Your new problum is
2x-3y=13
2x+4y=-8
Now subtract both problums
2x-3y=13
-2x+4y=-8
------------------
-7y=-21
Now divde the -7 on both sides.
-7y=-21
/7 /-7
---------------
y=2
Now you want to substitute the y for the 2 in on of your problums.
x+2(2)=-4
Now mutiplie the 2 by the 2
x+4=-4
Now subtract the 4 on both sides to solve for x.
x+4=-4
-4 -4
--------------
x=-8
Answer:
1
Step-by-step explanation:
Plug in -2.
f(x) = -6+7
f(x) = 1
14 is the GCF because 42 is divisible by 14
