Answer:
The answer is 258.
Step-by-step explanation:
If you do 64*2 you get 128.
Then add 1 which gives you 129.
Then add 57 to 129 to get 186.
Then last add 72 to get 258.

Step-by-step explanation:
<u>Step 1: Define Equation</u>
72 = 5x + 22
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 22 on both sides: 50 = 5x
- Divide 5 on both sides: 10 = x
- Rewrite: x = 10
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 72 = 5(10) + 22
- Multiply: 72 = 50 + 22
- Add: 72 = 72
Here we see that 72 does indeed equal 72.
∴ x = 10 is the solution to the equation.
Answer:
Option C.
Step-by-step explanation:
It is given that the first term of the arithmetic sequence is 8 and second term is 5.
We know that the explicit equation of an AP is
, where n is an integer greater than or equal to 1.
where, a is first term and d is common difference.
So, domain of this explicit equation is all integers where n ≥ 1.
Therefore, the correct option is C.
Is a isosceles triangle, follow the rule with 1:1:√2
24 squared is 576
576÷2=288
√288=16.970
so, 2 side is 16.970 inch
