3a x 3a x 3a x 3a x 3a

= 243a

Area = Length x Width

Since the pool is a square, you will do 243a x 243a

Area = 59,049

Sum of 4x^3+6x^2+2x^2-3 and 3x^3+3x^2-5x-5 is

spin [16.1K]

9514 1404 393

Answer:

7x^3 +11x^2 -5x -8

Step-by-step explanation:

Combine like terms.

(4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)

= (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)

= 7x^3 +11x^2 -5x -8

_____

Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...

(4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)

= (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)

= 7x^3 +9x^2 -3x -8

Sara covers the top of a box with squares of paper that are 1 square centimeter: she uses 48 squares with 6 squares in each row.

scZoUnD [109]

Answer:

Sarah makes 8 rows of squares.

Step-by-step explanation:

Given:

Number of squares she uses = 48

Number of squares in each row = 6

We need to find the number of rows she can makes.

Solution:

Let the number of rows she can make be $'x'$ .

Now we can say that;

Number of rows she can make is equal to Number of squares she uses divided by number of squares in each row.

framing in equation form we get;

$x=\frac{48}{6}=8\ rows$

Hence Sarah makes 8 rows of squares.

x:y =x: y

10: y =2:3

2y=30

y=15

y:z=y:z

15:z=3:5

3z=75
