Answer:
a = - 25
Step-by-step explanation:
Given that:
4a+6+16=-9(2+12a)-10(1-11a)
By simplifying:
- Adding like terms and multiplying constants into the bracket
- Negative sign will change the signs in the brackets
4a + 22 = -18 - 108a- 10 +110a
4a + 22 = -28 + 2a
- Taking terms with "a" to left side and others to right
- Signs of transferred terms will be changed
4a - 2a = -28 - 22
- Both terms on right side have negative sign so they wil be added and answer will have negative sign.
2a = -50
- Dividing both sides by 2 we get
a = -50/2
- Reducing to lowest term (dividing both by 2)
a = -25/

Which chapter is this ? ( i can help if i know this chapter ..)
Answer:
48cm^2
Step-by-step explanation:
First, you can break down this shape into two different, easier to work with shapes, with dimensions of 4*9 and 6*2. You can get this by cutting the bigger rectangle into the 4*9, and then using the 6*2 left over.
After that, all you need to do it multiply and then add.
4*9 is 36, and 6*2 is 12.
36+12=48
Hope this helped!
