Answer:
b = 1
Step-by-step explanation:
Given the equation is:
- 5b + 2b - (-b) + 7 = 5
We separate the terms of b and the constants. To do that we subtract 7 from both the sides. We get:
- 5b + 2b - (-b) + 7 - 7 = 5 - 7
⇒ - 5b + 2b - (-b) = - 2
Now, simplifying the terms with 'b'.
⇒ -5b + 2b + b = - 2
⇒ (-5 + 2 + 1)b = - 2
⇒ -2b = -2
Dividing both the sides by -2, we get:
b = 1 which is the required answer.

Answer:
-3
Step-by-step explanation:

Answer:
1/2 ×4 ×3=6
base is 4
and 3 is height
the answer is 6 as you multiply 1/2 ×base ×height
(-2+I)(3-6i)
-2i + -6i = 12i
