Answer:-2

Step-by-step explanation:

The slope intercept form of an equation is y=mx+b, where m is your slope and b your y int. If you compare the equations you can see that the slope is -1 and the y int is -2

the rectangle shown has a perimeter of 70cm and the given area. It’s length is 8 more than twice it’s width. Write and solve a s
vfiekz [6]

Dimensions of rectangle are:

Length = 26 cm

Width = 9 cm

Step-by-step explanation:

Perimeter of rectangle = 70 cm

Width= x

Length = 2x+8

We need to find the value of length and width of rectangle.

The formula used is:

Periemter\,\,of\,\,rectangle=2(Length+Width)

Putting values:

Periemter\,\,of\,\,rectangle=2(Length+Width)\\70=2(2x+8+x)\\70=2(3x+8)\\70=6x+16\\70-16=6x\\54=6x\\x=54/6\\x=9

So, Value of Width = x = 9 cm

Value of Length = 2x+8 = 2(9)+8 = 18+8=26 cm

So Dimensions of rectangle are:

Length = 26 cm

Width = 9 cm

Keywords: Perimeter of rectangle

First, find the arc measure BD. The arc measure is twice the central angle measure. BD should be 48*2 = 96.

The chord BC looks like it’s the diameter of the circle, so it must have a measure of 180.

From here you can find DC. The total measure of a circle is 360.
360- 96-180 = 84, so DC is 84.

DBC is 360- DC
so 360- 84 = 276.

DCB is just 360- BD
so 360- 96 = 264.
Hope this helps!
