A rectangle has a height of 5 and a width of 4x^2 – 2x – 6.
bogdanovich [222]

The area of the rectangle is 20x^{2} -10x-30 units.

Step-by-step explanation:

Step 1:

The area of a rectangle is obtained by multiplying the length with the width of the rectangle.

Considering this a whole rectangle, the length of the rectangle is 5 units and the width is the sum of 4x^{2}, -2x, and -6.

So the length of the rectangle = 5 units and

the width of the rectangle = 4x^{2} -2x-6 units.

The area of a rectangle = (length)(width).

Step 2:

By substituting the known values, we get

The area of the rectangle = (5) (4x^{2} -2x-6) = 20x^{2} -10x-30.

So the area of the rectangle is 20x^{2} -10x-30 units.

What is the equation of the line that passes through the point (6, 8) and has a slope 1/2
Korvikt [17]

Answer:

y=1/2x+5

Step-by-step explanation:

Plug it into the formula for a point and a slope.

(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))

Y-8=1/2(x-6)

Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.
