Answer:

20.

Step-by-step explanation:

2x + x - y^2; x = 8 and y = 2.

2(8) + 8 - (2)^2

= 16 + 8 - 4

= 24 - 4

= 20.

Hope this helps!

Answer:

= 20

Step-by-step explanation:

2x + (x - y²)

x = 8

y = 2

then:

2*8 + (8 - 2²)

= 16 + (8 - 4)

= 16 + 4

= 20

What is the distance between the points (-5,6) and (7,3)? a 8.06 b 12.37 c 11.40

julia-pushkina [17]

Hey there! I'm happy to help!

Here's how to find the distance between any two points.

Find the difference of the x values.

-5-7=-12

Square it.

-12²=144

Find the difference of the y values.

6-3=3

Square that.

3²=9

Add the two numbers we got.

144+9=153

√153≈ 12.37.

Have a wonderful day! :D

Well on this problem recall area of a rectangle is defined by:

A = lw our w = 1/6 and our l = (x + $\frac{2}{3}$ ) we have let 'x' represent our original length.
$(x + \frac{2}{3} )( \frac{1}{6} )= \frac{11}{72}$
$\frac{1}{6} x+ \frac{2}{18} = \frac{11}{72}$
12x + 8 = 11
12x = 11 - 8
12x = 3
x = $\frac{3}{12} = \frac{1}{4}$ So our original length is $\frac{1}{4}$
