Answer:

area=135

Step-by-step explanation:

The width is 9 and six more would make the length 15 which 15+15=30 and 9+9=18 which added together is 48 which would make the perimeter 48 which is what they told us the perimeter is so to find the area you multiply the 15 and 9 to get 135.

Answer:

135ft²

Step-by-step explanation:

Width = w

Length = w + 6

Perimeter = 48

Perimeter = 2(l + w)

Perimeter = 2(w + 6 + w) = 48

2(2w + 6) = 48

4w + 12 = 48

4w = 48 - 12

4w = 36

w = 36/4

width = 9

length = w + 6 = 9 + 6 = 15

Area = length × width

= 15 × 9

= 135 ft²

Ben is planning to fence his rectangular garden the area of the garden is 50 square feet and the length of the garden is twice t
swat32
Let L = Length, and W = Width. We are given the fact that L = 2W, and also know that the area = L x W = 50 square feet. So, by substitution: 2W x W = 50 sq ft, or 2W^2 = 50 sq ft, so W = sq rt (50/2) = 5 ft. Now, L = 2W = 2(5) = 10 ft. The perimeter of the fence is given by: 2L + 2W = 2(10 ft) + 2(5 ft) =20 ft + 10 ft = 30 ft. So, Ben needs 30 ft of fencing.

Solve y=3x-7 and 4x+3y=18 by substitution
Schach [20]

Answer:

x = 3

y = 2

Step-by-step explanation:

4x + 3(3x - 7) = 18 <em>Substitute</em><em> </em><em>y</em>

4x + 9x - 21 = 18 <em>Simply</em>

13x - 21 = 18 <em>Add</em><em> </em><em>like</em><em> </em><em>terms</em>

13x = 39 <em>Add</em><em> </em><em>2</em><em>1</em>

x = 3 <em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>3</em>

y = 3(3) - 7 <em>Substitute</em><em> </em><em>x</em>

y = 9 - 7 <em>Simply</em>

y = 2 <em>Subtract</em>

Let's check:

4(3) + 3(2) = 18

12 + 6 = 18

18 = 18

It works!

Consider the function ( ) round( ) f xx , which rounds the input, x, to the nearest integer. Is this function one-to-one? Expla
jek_recluse [69]

Answer:

It is not a one to one function

Step-by-step explanation:

Required

Determine if f(x) = round(x) is a one to one function

This question is best answered using illustrating values;

Let x = 1.1

f(x) = round(x) becomes

f(1.1) = round(1.1)

f(1.1) = 1

Let x = 1.3

f(x) = round(x) becomes

f(1.3) = round(1.3)

f(1.3) = 1

Notice that for the two values of x, f(x) has the same value of 1.

This two illustrating values can be used to conclude that the fuction is not one-to-one.
