A rectangle has a length (x2 + 4y) unit and a breadth of (-2x + y3) unit. Find its perimeter

Mathematics
1 answer:
Ivahew [28]3 years ago
6 0

Step-by-step explanation:

how do we find area? Length x width, right?

 

Let's break up each part.

 

3x3y2 = 3(x)(x)(x)(y)(y)

5x2y3 = 5(x)(x)(y)(y)(y)

 

Combining everything we have, 3(5)(x)(x)(x)(x)(x)(y)(y)(y)(y)(y). That's 15x5y5.

 

We multiply the coeffiecients and add exponents with the same base.  

 

Hope this helps!

A group of 86 people consist of men women and children. There are twice as many women then there are men. There are 6 more child
weqwewe [10]

Answer: 16 men

32 women

38 children

Step-by-step explanation:

Let x represent the number of men in the group.

Let y represent the number if women in the group.

Let z represent the number of children in the group.

A group of 86 people consist of men women and children. This means that

x + y + z = 86 - - - - - - - - - - - - 1

There are twice as many women than there are men. It means that

x = y/2

There are 6 more children than there are women. This means that

z = y + 6

Substituting x = y/2 and z = y + 6 into equation 1, it becomes

y/2 + y + y + 6 = 86

multiplying through by 2, it becomes

y + 2y + 2y + 12 = 172

5y = 172 - 12 = 160

y = 160/5 = 32

x = y/2 = 32/2

x = 16

z = y + 6 = 32 + 6

z = 38

Greg have 24 more stickers than Wayne and Ronald have twice as much stickers than Wayne together they have 124 stick how much ea
lukranit [14]
G=24+w
r=2w
g+w+r=124
Substitute the values to get 24+w+w+2w=124
Simplifies to 4w=100. Therefore, Wayne has 25. Greg has 24 more than Wayne, so he has 49. Ronald would have 50.
