2a 3x4a +3x-5
2a+12a-15
14a-15
i think thats the answer
Answer:
Step-by-step explanation:
m+2/2 = 1/2
m=0.5
so
2m+4=5 is the correct answer
Answer:
x=30o+n90on∈Z
Step-by-step explanation:
cos2x=sin(90o−2x)=sin(2x−30o)
Which mean 90o−2x=2x−30o+n360o
or 90o−2x+2x−30o=(2n+1)180o
The later cannot be true.
so x=30o+n90on∈Z
The length is 7 and the width is 3
100, because in 3,492, it is in the hundreds place. In 704, it is in the one's place. 100/1 is 100. So 100 times greater.
