Let the width = x then length = x + 11 inches

Perimeter of a rectangle = 2*width + 2*length so we have the equation:-

( letting P = perimeter , L = length and W = width)

P = 2L + 2W

86 = 2(x + 11)) + 2x

86 = 4x + 22

4x = 86-22 = 64

x = 64 / 4 = 16 inches

Therefore the length of the rectangle = 16 + x

= 16 + 11 = 27 inches Answer

How do you solve the system?<br> y=9-2x<br> x+5y=0

AnnyKZ [126]

Well, so the x+5y= 0 you can make this into x=-5y and then plug this in into ( y=9-2x) the -2x , which these would become y=9-2(-5y) simplify and equals to y=9+10y. Then you simplify much smaller y=-9. Now that you have the y number you just plug this in into x=-5y, which these becomes x=-5(-9) and the answer is x=45. At the end you just need to find the x and y, so the answer is x=45 and y=-9 . Hopefully this would make this much easier to you.

pat calculated tan(88)° and obtained a value of 28.6363, but isn't sure what that value means in context. write at least one sen

coldgirl [10]

Step-by-step explanation:

tangent is the ratio of opposite (o) to adjacent (a). it means when an angle is getting bigger, it will impact to the ratio of o/a and reaching infinite value at the angle 90°.
