Mathematics
1 answer:
Firdavs [7]3 years ago
7 0

Answer:

A: 5x^2 + 42x + 16

B: 12x + 20

C: 351 units

Step-by-step explanation:

A: (5x + 2) * (x + 8) is the same as x(5x + 2) + 8(5x + 2). You just need to solve and simplify that for the area:

x(5x + 2) + 8(5x + 2)

= 5x^2 + 2x + 40x + 16

= 5x^2 + 42x + 16

B: You need to do 2l + 2w, or 2(5x + 2) + 2(x + 8):

2(5x + 2) + 2(x + 8)

= 10x + 4 + 2x + 16

= 12x + 20

C: You can either replace the x in the equation with 5 or replace the x in the figure itself with 5. I will replace the one in the figure with 5 because it is a lot easier:

(5(5) + 2) * (5 + 8)

= 27 x 13

= 351 units

On a unit circle, the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal distan
zalisa [80]

Answer:

(2√5)/5

Explanation:

CHECK THE ATTACHMENT BELOW FOR DETAILED EXPLATION

From the question we can deduced that the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal distance, we can say that the y-coordinate, is twice of the horizontal, then let call the horizontal "y", the vertical would be 2y.

from the attachment the question on the unit circle is interpreted using a figure,then, hypotenuse was first calculated

Identify the type of slope and then find the slope of the line.
Irina18 [472]

Answer:

  • -1/2, negative slope

Step-by-step explanation:

As per graph it is visible that the slope is negative, it goes down when x-value increases

<u>Use two points to find the slope:</u>

  • (-4, -1) and (0, -3)

<u>Slope formula:</u>

  • m = (y2 - y1)/(x2 - x1)

<u>Value of the slope:</u>

  • m = (-3 - (-1))/(0 - (-4)) = -2/4 = -1/2
