Answer:
a rational number
Step-by-step explanation:
3.4 is a terminating decimal. That means that after the 4 in 3.4 there are no other numbers (the number "ends" after the 4) Also, 3.4 can be written as a RATIO of two numbers (looks like a fraction)
3.4 = 3 4/10 = 3 2/5
= 15/5 + 2/5
= 17/5
If you put 17÷5 in a calculator it would say 3.4
3.4 = 17/5
3.4 is a rational number.
Use Pythagorean thrm
17^2+10^2=21^2
289+100=441
389≠441
This is not a right triangle
Answer:
Step-by-step explanation:
3(x+4)-6=5x+5
distribute 3 through the parenthesis (3 times x + 3 times 4)=3x+12
3x+12-6=5x+5
subtract 12-6
3x+6=5x+5
Move the variable to the left and change the sign
3x-5x+6=5
collect like terms
3x-5x=5-6
-2x=5-6
divide both sides by -2
x=1/2
