1 answer:

5 0

The integers are 10 and 12.

The square of 10 is 100, and the square of 12 is 144.

The sum of 100 and 144 is 244.

10 and 12 are both even numbers.

Answer:

B. 81 weeks

Step-by-step explanation:

If we plug everything into the equation it should look like this:

$82 = w + 1$

Then we would subtract 1 from both sides, then we are left with w:

$w = 81$

Hope this helps!

Look at the picture.

We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:

$\dfrac{x}{8}=\dfrac{15}{5}$

$\dfrac{x}{8}=3$ multiply both sides by 8

$\boxed{x=24\ in}$

If n ∈ $\mathbb{N}$ then
$U_{0}=3(0)-1=-1$
$U_{1}=3(1)-1=2.$
$U_{2}=3(2^2)-1=11.$
$U_{3}=3(3^2)-1=26.$
