Answer:

So I'd say 20in^2 or 22in^2.

Step-by-step explanation:

I decided to make it into a full pentagon shape to just estimate.

So a pentagons sides are all equal so I counted the amount in boxes on the sides of the regular shape and most of them would be 3.5 if you changed the shape into a pentagon.

And I got:

--> 21.076

Natasha2012 [34]

Answer:

Yes, because if you substitute 10 for r in the equation and simplify, you find that the equation is true.

Step-by-step explanation:

$\frac{r}{4} = 2.5 \\ lhs = \frac{r}{4} \\ = \frac{10}{4} \\ = 2.5 \\ = rhs \\ \therefore \: \frac{r}{4} = 2.5 \\$

Determine if the following sequence is an Arithmetic Sequence. If it is, what would be the 31st term? NOTE: an=a1+(n-1)d

Ivan

<h3>Key points :-</h3>

᪥ The formula to find the 31st term is : $\sf \: a_{n} = a_{1} + (n - 1) \times d$

᪥ In the formula, $\sf \: a_{1}$ represents the first term of the sequence.

᪥ $\sf\:n$ is the number of terms, In our case n is 31.

᪥ $\sf\:d$ is the common difference between the terms, In our case d is 4.
