The formula of a perimeter of a rectangle:

P=2(l+w)

We have:

P=120\ in\\\\l=w+10

Substitute

2(w+10+w)=120\\\\2(2w+10)=120\ \ \ \ |:2\\\\2w+10=60\ \ \ \ |-10\\\\2w=50\ \ \ \ |:2\\\\w=25\\\\l=25+10=35

<h3>Answer: Length = 35 in, Width = 25 in.</h3>

tatiyna
ANSWER

f( - 1) = 2

EXPLANATION

The given function is a piecewise defined function.

f( - 1)
is the y-value that corresponds to
x = - 1.

To determine that y-value, we need to trace from
x = - 1
to where it meets the graph.

We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.

From the graph, we can see that this x-value corresponds to a y-value of
2

This implies that, when
x = - 1,y = 2

Therefore
f( - 1) = 2
See graph.

the length of a rectangle is twice its width the perimeter is 48 cm what are the dimensions of the rectangle
inysia [295]

Answer:

The length=16cm and the width=8cm.

Step-by-step explanation:

Given that the length is twice the breadth or width of the rectangle

Let's assume that the breadth of the rectangle is x.

Thus the length is 2x.

Given perimeter=48cm

The formula for the perimeter of a rectangle is 2(l+b) where l is length and b is breadth.

2(x+2x)=48

(3x)=48/2

3x=24

x=8cm

2x=16cm
