Help pls!?!?!?!!! This is algebra 2

Tresset [83]

$\boxed{\sf a_n=\dfrac{(-1)^n}{5n}}$

a:-

$\\ \sf\longmapsto a_1=\dfrac{(-1)^1}{5(1)}$

$\\ \sf\longmapsto a_1=\dfrac{-1}{5}$

$\\ \sf\longmapsto a_1=-5$

b:-

$\\ \sf\longmapsto a_4=\dfrac{(-1)^4}{5(4)}$

$\\ \sf\longmapsto a_4=\dfrac{1}{20}$

c:-

$\\ \sf\longmapsto a_{30}=\dfrac{(-1)^{30}}{5(30)}$

$\\ \sf\longmapsto a_{30}=\dfrac{1}{150}$

d:-

$\\ \sf\longmapsto a_{19}=\dfrac{(-1)^{19}}{5(19)}$

$\\ \sf\longmapsto a_{19}=\dfrac{-1}{95}$

In a certain hexagon, the two shortest sides have the same length. The length of each remaining side is 2 inches more than the l

Nonamiya [84]

Answer:

length of the shortest side = 5 inches

length of the longest side is 7 inches

Step-by-step explanation:

Hexagon has 6 sides

Let x be the shortest side

length of the longest side is x+2

there are 2 shortest sides and 4 longest sides

To find perimeter we add all the sides

$Perimeter = 2(x) + 4(x+2)$

$38= 2(x) + 4x+8$

$38=6x+8$

Subtract 8 from both sides

$30=6x$

divide both sides by 6

x=5

length of the shortest side = 5 inches

length of the longest side is 7 inches

Write as a product: −y^3+xy^2−4x+4y

Semmy [17]

Answer:

$(x-y)\left(y^{2}-4\right) \text { is the product of }-y^{3}+x y^{2}-4 x+4 y$

Step-by-step explanation:

$\text { Given equation is }-y^{3}+x y^{2}-4 x+4 y$

$\text { Writing all }^{a} x^{\prime \prime} \text { terms and "y" terms at a place. }$

$\left(-4 x+x y^{2}\right)+\left(4 y-y^{3}\right)$

Now take “x” common in the first term and “y” common in second term then the equation becomes as follows:

$x\left(-4+y^{2}\right)-y\left(-4+y^{2}\right)$

$x\left(y^{2}-4\right)-y\left(y^{2}-4\right)$

$(x-y)\left(y^{2}-4\right)$

$\text { The product of the given equation is }(x-y)\left(y^{2}-4\right)$
