Answer:
remember powers is like multiplying that number by itself 3x3x3x3x3x3x3x3x3x3x3 ÷ 3x3x3x3
the second problem 3x3x3 × 3
(If that helps
45
1. Area = 1/2 B(base) x H(height)
2. Area = 1/2 9 x 10
3. Area = 1/2 90
4. Area = 45 inches
Answer:
Last choice. d.
Step-by-step explanation:
We are given the first term and the sixth term.
The first term is
.
The sixth them is
.
Let's solve for the common ratio, r.

Divide both sides by -9:

Take the fifth root of both sides:


So the common ratio is 4.






Answer:
Therefore the results from adding the equation in this system is

Step-by-step explanation:
Given:
Equations as
.......................1
.......................2
To Find :
Result when adding equation 1 and 2 = ?
Solution
On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18) as shown below
11x - 3y = -17
-4x + 3y = - 18
-------------------------------------------
7x + 0 = - 35
---------------------------------------------
Therefore the results from adding the equation in this system is
