4(u+3)+3u=-2
distribute: 4u+12+3u=-2
simplify: 7u+12=-2
isolate the variable: 7u=-14
divide: u=-2
check answer: 4(-2+3)+3(-2)=-2
-8+12-6=-2
-2=-2
therefore, u= -2
Answer:
36!
Step-by-step explanation:
Parallelogram's formula:
6 x 6 = 36
In this case 6 is your base and 6 is your height so we just multiply the two given lengths to get the area!
The fraction form would be 21/4. The decimal form would be 5.25.
This equation has one solution which is -1.5
3x+7=-3x-2
+2. +2
3x+9=-3x
-3x. -3x
9= -6x
/-6. /-6
X= -1.5
