(4x-7)(3x-1)-(3x-5)(5x-1)

Mathematics
1 answer:
zloy xaker [14]4 years ago
6 0

Answer:

(4x-7)(3x-1)-(3x-5)(5x-1)=-3x^2+3x+2.

Step-by-step explanation:

Calculate the expressions in brackets separately:

1. (4x-7)(3x-1)=4x\cdot 3x+4x\cdot (-1)+(-7)\cdot 3x+(-7)\cdot (-1)=12x^2-4x-21x+7=12x^2-25x+7.

2. (3x-5)(5x-1)=3x\cdot 5x+3x\cdot (-1)+(-5)\cdot 5x+(-5)\cdot (-1)=15x^2-3x-25x+5=15x^2-28x+5.

Then

(4x-7)(3x-1)-(3x-5)(5x-1)=(12x^2-25x+7)-(15x^2-28x+5)=12x^2-25x+7-15x^2+28x-5=-3x^2+3x+2.

A rectangle has an area of 4 square centimeters. A second rectangle is 3 times as long and 3 times as wide as the first rectangl
vekshin1

Answer:

The area of the second rectangle will be 36 square centimetres

Step-by-step explanation:

Given:

Area of the first rectangle  =  4 square centimetres

A second rectangle is 3 times as long and 3 times as wide as the first rectangle

To Find:

Area of the second rectangle = ?

Solution:

We know that area of the rectangle is  Length X breadth

Length X width = 4

In this case the are 2 possibilities

Case 1:

Length = 2 cm

Width  = 2 cm

2 X 2 = 4

Now According to the question

Length is 3 times  = 2 X 3 = 6cm

width is also 3 times  = 2 X 3 = 6 cm

Now the area of the second rectangle will be

6 X  6 = 36 square centimetres

Case 2:

Length = 4 cm

Width  = 1 cm

4 X 1 = 4

Now According to the question

Length is 3 times  = 4 X 3 = 12 cm

width is also 3 times  = 1 X 3 =3 cm

Now the area of the second rectangle will be

12 X  3 = 36 square centimetres
