Answer:

21

Step-by-step explanation:

All three sides are equal

2x-7 = x+y-9 = y+5

Using the last two

x+y-9 = y+5

Subtract y from each side

x+y-9-y = y+5-y

x-9 = 5

Add 9 to each side

x -9+9 = 5+9

x=14

We know the side length is

2x-7

2(14) -7

28-7

21

The side length is 21

Solve for x in the parallelogram.<br><br><br><br> The solution is x= <br> units.
natka813 [3]

\textit{area of a parallelogram}\\\\ A=bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ b=13\\ A=104\\ h=x \end{cases}\implies 104=(13)(x)\implies \cfrac{104}{13}=x\implies 8=x

How to solve this showing all work ! Also explain why they aren’t polynomials if you can :)
Lesechka [4]

Polynomials are linear combinations of positive integer powers. For example,

x^{100}+30x^2-\sqrt 2\,x+21

is a polynomial, but

-x^{-1}-4x^\pi+x^{3/2}

is not.

(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of a and b is k_1a+k_2b, where k_1,k_2 are any numbers.)

8x^2-18\sqrt x+5x-3 is not a polynomial; the offending term is -18\sqrt x, or -18x^{1/2}.

B\7+12=-8 helpppppppp
vodka [1.7K]

Answer:

b = -152

Step-by-step explanation:

  1. 7 + 12 = 19
  2. Plug 19 in: \frac{b}{19} = -8  
  3. Multiply each side by 19 to cancel out the 19 under b. It should now look like this: b = -152

I hope this helps!
