Let x= width
Length= 5x-4
2(x)+2(5x-4)=160
2x+10x-8=160
12x-8=160
+8. +8
12x=168
x=14
width=14
length= 5(14)-4=66

Someone please help me I’ve been trying all day!<br><br> NO LINKS , answers only <br> I MEAN IT!!!!
DedPeter [7]

Answer:

Step-by-step explanation:

You want to set up a system. We are given some points fo we can set up inputs and outputs. F(0) = 5, given by point (0,5). and F(3)=135, given by point (3,135). The exponential function general equation is F(x)= a(b)^x. plug in out functions into the general equation to get a(b)^0=5 and a(b)^3=135. Then you simplify and solve for a. In the equation a*b^0=5, anything to the power of 0 is 1. so a*1=5. Therefore a=5. we plug in the a to the second equation to find b. 5*b^3=135. b^3=27. b=3 from simplifying. Therefore, the equation should be 5(3)^x. THATS IT!

Which of the following demonstrates how the 20 is calculated using the combination pattern​
UNO [17]

The combination expression that demonstrates how the 20 is calculated using the combination pattern​ is 6C3

<h3>Permutation and Combination</h3>

While combination has to do with selection, permutation has to do with arrangement.

According to the combination rule

nCr = n!/(n-r)!r!

The expression that gives the result of 20 is expressed below;

6C3 = 6!/(6-3)!3!

6C3 = 6!/3!3!

6C3 = 6!/6*6
6C3 = 720/36
6C3 =20

Hence the combination expression that demonstrates how the 20 is calculated using the combination pattern​ is 6C3
