The sum of four consecutive integers is 78. What<br> are the 3rd and 4th integers?

IRINA_888 [86]

Answer:

20, 21

Step-by-step explanation:

The number halfway between the middle two integers is the average of the four:

78/4 = 19.5

Then the four integers are 18, 19, 20, 21.

The 3rd and 4th integers are 20 and 21.

A rectangle with a perimeter of 19m^2+2m-10 and a width of m^2 write an expression for the lenght

never [62]

Answer: $\frac{17}{2}m^2+m-5$

Step-by-step explanation:

By definition, the perimeter of a rectangle is:

$P=2l+2w$

Where "l" is the lenght and "w" is the width.

If you solve for "l":

$P-2w=2l\\\\l=\frac{P-2w}{2}$

In this case, you know that the following expression represents the perimeter of the rectangle:

$19m^2+2m-10$

And the width of that rectanle is represented wih this expression:

$m^2$

Therefore, based on the explained above, you can conclude that the lenght of that rectangle is given by:

$\frac{19m^2+2m-10-2(m^2)}{2}$

Finally, simplifying the expression, you get:

$=\frac{17m^2+2m-10}{2}=\frac{17}{2}m^2+m-5$

Given trapezoid WXYZ, what is XY?

stepan [7]

Answer:

XY = 16 ft

Step-by-step explanation:

The mid segment DE is half the sum of the parallel bases, that is

$\frac{XY+WZ}{2}$ = 20 ( multiply both sides by 2 to clear the fraction )

XY + WZ = 40

XY + $\frac{3}{2}$ XY = 40 ( multiply through by 2 to clear the fraction )

2XY + 3XY = 80

5XY = 80 ( divide both sides by 5 )

XY = 16
