Answer:

2x^2 - x - 1

Step-by-step explanation:

Lets rewrite it to the area formula

(2x+1)(x-1)

Simplify-(distributive property of multiplication)

(2x*x) + (2x*-1) + (1*x) + (1*-1) =

Simplify

2x^2 + (-2x) + x + (-1)

Simplify

2x^2 - x - 1

The answer is 2x^2 - x - 1

If my answer is wrong, pls correct me

Which points are on the graph of g(x) = (1/5)^x

11111nata11111 [884]

Answer:

A) The point( -1 , 5) is satisfies the given graph $g(x) = (\frac{1}{5} )^{x}$

B) The point( 3 , 1/125) is satisfies the given graph $g(x) = (\frac{1}{5} )^{x}$

Step-by-step explanation:

Explanation:-

Given graph

y = $g(x) = (\frac{1}{5} )^{x}$

Put the point ( -1 , 5)

Put y =5 and x =-1

$5 = (\frac{1}{5} )^{-1} = 5$

The point( -1 , 5) is satisfies the given graph

ii)

Given graph

y = $g(x) = (\frac{1}{5} )^{x}$

$\frac{1}{125} = (\frac{1}{5} )^{3} = \frac{1}{125}$

The point( 3 , 1/125) is satisfies the given graph $g(x) = (\frac{1}{5} )^{x}$

I need help plzzzzzzzzzzzzzzzzzzzzzzzz

Neporo4naja [7]

We can find the value of x through a proportion. Since these two triangles are similar, their sides are in proportion.

4 is to 12 as 5 is to x
Remember to say 12, not 8! 8 is only part of the whole side. We can also simplify 4 is to 12 to 1 is to 3.

1/3 = 5/x
Cross multiply
x = 15
Hope this helps!

Michelle is building shelves for her room. She has a plank 137 inches long that she wants to cut into 7 shelves of equal length.

bixtya [17]

Because she cut off a total of 4 inches, the plank is now 133 inches long. Divide 133 by 7 to get her 7 equal parts, and each shelf will be 19 inches.
