Answer:
All real numbers
Step-by-step explanation:
There is no real number that makes the expression undefined, therefore the domain would be all real numbers.
Answer: D) x+4+x+4
The two x terms combine to x+x = 2x
The other pair of like terms, the constants, add to 4+4 = 8
Overall we get 2x+8
2x+8 is also equivalent to 2(x+4) when you factor out the GCF 2.
It need to be at least 50 ft long and 50 ft wide.
<span>-5(3t-5)+7t=8t-6
-15t + 25 + 7t = 8t - 6
-15t + 7t - 8t = -6 - 25
-16t = -31
16t = 31
t = 31/16 = 1.9375</span>
