</span> (2x - 3)(3x +4)
Answer:
x=-4
Step-by-step explanation:
First, write the expression and distribute.
-2(2x+11)=5x+14
-4x-22=5x+14
Add one of the variables to the other side (it makes solving a lot easier). I'll add 4x to both sides because it won't result in a negative x.
-4x-22=5x+14
<u>+4x +4x</u>
-22=9x+14
Now, subtract 14 on both sides.
-22=9x+14
<u>-14 -14</u>
-36=9x
Divide both sides by 9.
-36=9x
<u>/9 /9</u>
-4=x or x=-4 (they both mean the same thing)
Have a wonderful day! I hope this helped :3
Answer:
The answer is multiplying by -2
Step-by-step explanation:
Answer:
It means that above 0 degrees Celsius the water does not freeze, whereas 0 degrees are freezing teperatures of water.
Step-by-step explanation:
Water freezes at 0 degrees Celsius, but the freezing temperature can be lowered by adding salt to the water. A student discovered that adding half a cup of salt to a gallon of water lowers its freezing temperature by 7 degrees Celsius. What is the freezing temperature of the gallon of salt water?
0° - 7° = -7°
