Answer:
This is GP and number of terms is 10 first term is 1 ratio is 3/2
Step-by-step explanation:
- Using the formula u get sum as 113.33 (didn't calculate in fraction)
Answer:
First factor the Area
Area = 18x2+12x+2
Factor out a 2
Area = 2(9x2+6x+1)
Factor this and you get
Area=2(3x+1)(3x+1)
Let L be Length and W be Width
Area=LW
and the Length is twice the Width so
L=2W
Area=2(3x+1)(3x+1) so
L=2(3x+1)
W=3x+1
This can also be written as if you distribute the 2
L=6x+2
W=3x+1

<u>Algebra II</u>
- Complex Standard Form: a + bi
- Imaginary Numbers
Step-by-step explanation:
<u>Step 1: Define expression</u>
(8 + 9i) + (5 - 9i) - (8 - 7i)
<u>Step 2: Simplify</u>
- Distribute negative: 8 + 9i + 5 - 9i - 8 + 7i
- Combine like terms: 5 + 7i
