Answer:
4
Step-by-step explanation:
because The square root of 16 is 4, which is a rational number.
6x−12+2x=3+8x−15
Simplify:
6x+−12+2x=3+8x+−15
(6x+2x)+(−12)=(8x)+(3+−15)(Combine Like Terms)
8x+−12=8x+−12
8x−12=8x−12
Subtract 8x from both sides.
8x−12−8x=8x−12−8x
−12=−12
Add 12 to both sides.
−12+12=−12+12
0=0
The real numbers are the only solution we can have.
5x and 7y. Keep up the good work
If you divide 4/25 it equals 16%. Or another way you can do it is you multiply 25 by 4 to get 100 then just multiply 4 by 4 also and it gets you 16/100 which equals 16%.
Replace the x with 2: f(2)=2*2+7=4+7=11
replace the x with 7: f(7)=2*7+7=14+7=21
