Answer:

Circle 1=6x+2y

Rectangle 4 = 3x+y

Circle 4 = 5x

Step-by-step explanation:

4x+3y and 2x-y can be added to find result for the circle.

Let C1 represent circle 1

4x+3y+2x-y=C1\\

Combining\:like\:terms\\

4x+2x+3y-y=C1

6x+2y=C1

So, The result is: C1=6x+2y

Now, We need to solve:

Let R1 represent rectangle 4

x+4y + R1 = 4x+5y

R1=4x+5y-(x+4y)

R1=4x+5y-x-4y

R1=4x-x+5y-4y

R1=3x+y

So, Solving x+4y + R1 = 4x+5y, We get R1 = 3x+y

Now, We need to solve the equation:

Let C4= Circle 4

2x-y+3x+y=C4

Combining the like terms

2x+3x-y+y=C4

5x=C4

So, Solving 2x-y+3x+y=C4 we get C4 = 5x

Factor 21c+24.<br> Write your answer as a product with a whole number greater than 1.<br> use ()
Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

21c+24=3\left(7c+8\right)

Step-by-step explanation:

Given the expression

21c+24

Determining the factor

21c+24

  • Rewrite 24 as 3 · 8
  • Rewrite 21 as 3 · 7

so the expression becomes

21c+24=3\cdot \:\:7c+3\cdot \:\:8

Factor out the common term 3

             =3\left(7c+8\right)

Therefore, the required answer as a product with a whole number greater than 1 will be:

21c+24=3\left(7c+8\right)

Answer:

the side of a square is 45 m

Step-by-step explanation:

The computation of the side of the square field that contains the similar area as compared with rhombus is given below:

As we know that

Area of rhombus = Base × Altitude

= 81 × 25

= 2025

And, area of Square =  Side × side

2025 = side^2

side  = √2025

= 45m

Hence, the side of a square is 45 m
