Hiya!

x is going to work out to 25.

———————————————

so first put the numbers into the equation you’ve been given.

pressure is 3, force is 1500 so 3=1500/area

then rearrange this equation so that you’re finding area.

area=1500/3

and 1500/3 gives you 500.
so 500 is the area.

area is length multiplied by width, so 20 multiplied by x.
total/width will give length, so 500/20 will give x.
500/20=25

so x is 25.

Answer:

The first one is missing (d - 9) so it would be 5(d -9) or when you factor it out 5d - 45

In the second one (d + 7) is missing so it will be 8d(d + 7) so if you factor that out you will receive 8d^2 + 56

Step-by-step explanation:

3d^2 + 18d -21 =(3d -3)( d + 7)

3d^2 -30d +27 =(3d -3)(d - 9)

A dinner platter is in the shape of a regular decagon the platter has an area of 161 in.² and a side length of 4.6 inches what's
cupoosta [38]
Number of sides= 10
Side length= 4.6 ( or in this case base)

161 sq inches / 10 = 16.1 area of triangle.

Area of triangle =(b<span>ase * </span>height)/2 

16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)

32.2=4.6*h
divid 32.2 by 4.6

<span>7 is the height of the triangle</span>
