The length of a rectangle is 4 times its width and the perimeter is 150 feet.

We know that L = 4W, and P = 2l + 2w, so 150 = 2L + 2w
So, 150 = 2*4w + 2w
150 = 8w + 2w
150 = 10w
w = 150/10
w=15
So, the Width of the Rectangle is 15 feet.
And if they asked you to find the length,
L = 4W
L = 4*15
L=60
so, the Length will be 60 feet.

Hope this Helps! :)

Let width be x So 2(x+4x)=10x=150 x = 15 feet

Evaluate: x(y – z) for x = 3, y = 9, and z = 2 O 33 O 45 O-21 O 21

ad-work [718]

Answer:

Step-by-step explanation:

Hi there!

We are given the expression x(y-z), and we want to evaluate it if x=3, y=9, and z=2

As we're given the values of the variables, we can substitute those values into the expression to find out what the value of the expression is.

So substitute 3 as x, 9 as y, and 2 as z in the expression above

x(y-z)

3(9-2)

Now we must follow the order of operations; start by subtracting 2 from 9 (do the stuff inside the parentheses first)

3(7)

Now multiply 3 and 7 together

21

Which values of P and Q result in an equation with no solutions? 83x+P=83x+Q

aleksandr82 [10.1K]

83x+P=83x+Q

subtract 83x from each side

P=Q

if P does not Q there are no solutions

the lines would be parallel and never intersect if Q does not equal P
