Answer:

D.  (21x2 - 17x + 2)\text{ square units }

Step-by-step explanation:

Given,

The length of the rectangle = (7x-1) unit,

Its width = (3x-2) unit,

We know that,

The area of a rectangle = Length × Width

So, the area of the rectangle,

A=(7x-1)(3x-2)

=(7x-1)(3x)-(7x-1)(2)  ( Distributive property )

=21x^2-3x-14x+2     ( Again by distributive property )

=21x^2-17x+2

Hence, Option D is correct.

Which is a qualitative graph? On a coordinate plane, a line with positive slope goes through points (negative 1, 0) and (0, 3).
guapka [62]

Answer:

(-1,0), (0,3) and (2,2.25)

Step-by-step explanation:

The qualitative graph is as follows:

A(-1,0) ------> B(0,3) ------> C(2,2.25)

Hence, slope = (2.25 - 0)/(2 - (-1)) = 2.25/3

∴ slope = 0.75

0 = 4 + n/5 two step equations​
Serjik [45]

Answer: n= -20?

Step-by-step:

Simplify both sides of the equation

1/5n+4=0

Then subtract 4 from both sides

1/5n + 4 - 4 = 0 - 4

1/5n= -4

Then multiply both sides by 5

5*(1/5n)=5*(-4)
