find the dimensions of a rectangle that has a length 3 inches longer than it’s width and has an area of 40in^2
Gnom [1K]

<u><em>Answer</em></u>

length: 8 inch and width: 5 inch

<u><em>Explanation</em></u>

Let width be x,

then the length: x + 3

solve:

\sf (x+3)(x) = 40

\sf x^2+3x = 40

\sf x^2+3x-40=0

\sf x^2+8x-5x-40=0

\sf x(x+8)-5(x+8)=0

\sf (x-5)(x+8)=0

\sf x = 5 \ or \  -8

  • As width cannot be negative, width will be 5.

Find for length:

\sf x + 3

\sf  5+ 3

\sf 8

Is y=11 a function and why
Mariana [72]
Y=11 is a function, because a function is a set of numbers where for you only have one input for every output. In this case it is a one kt one function because there is only one output for every input. Every input results in 11, therefore this is a function.

100 POINTS!!!
jenyasd209 [6]

Answer:

It's actually an  enlargement  of the figure.

Step-by-step explanation:

Because if the figure originally was M' (-2,2), S' (4,2), V' (2, -2). And now the shape is M (-3, 3), S (6, 3), V ( 3, -3). This means that the Triangle got bigger.

The scale factor of the smaller shape inside of the bigger shape is 2 and the scale factor of the bigger shape is 3 making the bigger shape well bigger.
