3 0

Answers:

1.  No I don't agree with Selena because the area of the rectangle has the exact same area of the square

Step-by-step explanation:

1.     square = x

rectangle length = 6 + x

rectangle width = x - 6

the plus 6 and minus 6 cancel each other out and make the same area that the square has.

Im sorry i dont know what the answe to 2 is.

Jethro used dimensional analysis to convert one rate of speed to another. Two of the conversion factors he used are 5280 ft/1 mi
NNADVOKAT [17]

The units of the initial and final rates of speed are;

<u><em>Initial rate of Speed = ft/hr</em></u>

<u><em>Final rate of speed = mi/min</em></u>

  • We are told that the conversion factors he used are;

5280 ft/1 mi and 1 hr/60 min

  • Now, the meaning of 5280 ft/1 mi denotes that;

5280 ft mile is equivalent to 1 mile

This means that the initial distance <em>unit </em>used was ft while the final one was mile

Also, 1 hr/60 min denotes that;

1 hour is equivalent to 60 minutes.

This means that the initial time units used was hour while the final one was minute.

  • In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.

Calculate the slope of the line through the points M(-2, -1) and N(0, -13).
galina1969 [7]

Answer:-6

Step-by-step explanation:

to solve for slope, you have to do (y1-y2)/(x1-x2)

in this problem, that turns into (-1-(-13))/(-2-0)

which is (-1+13)/(-2-0) which is 12/-2 which is -6, your answer

Use point-slope form to write the equation of a line that passes through the point
blagie [28]

Answer:

y - 8 = -2(x - 9)

Step-by-step explanation:

Given the slope, m = -2, and the point, (9, 8):

Let (x₁, y₁) = (9, 8)

slope (<em>m </em>) = -2

We can substitute these values into the following <u>point-slope form</u>:

y - y₁ = m(x - x₁)

y - 8 = -2(x - 9)  ⇒ This is the point-slope form.

Help? :)
Dimas [21]

Answer:

16


Step-by-step explanation:

Area = perpendicular height * base

=  DP * CB

=  √[(2 - -1.2)^2 + (-5 - (-3.4)^ ] *  √[(2 - 0)^2 + (3- -1)^2)]

= √(12.8.) * √(20)

=  16
