➷ Here are the steps to solving that problem:

(2x+1)^2

=(2x+1)(2x+1)

=(2x)(2x)+(2x)(1)+(1)(2x)+(1)(1)

=4x^2+2x+2x+1

=4x^2+4x+1

What is the best estimate for the quotient 5,397 divided by 62

marysya [2.9K]

Answer:

The best estimate is 90.

Step-by-step explanation:

Given : Quotient 5,397 divided by 62 .

To find : The best estimate of the given situation.

Solution : We solve this by approximating the term and then divide to get solution.

Approximation is rounding off the number

→ When the ones digit is greater than 5 (5, 6, 7, 8, or 9) then it round the number up.

→ When the ones digit is less than 5 ( 0, 1, 2, 3, or 4) then it round the number down.

Approximation of 5397 to hundredth is 5400

Approximation of 62 to tenth is 60

Now, divide 5400 by 60

$\frac{5400}{60}= 90$

Therefore, The best estimate is 90.

We can also cross check by actual division of 5397 by 62.

$\frac{5397}{62}= 87.04$

When we approximate 87.04 it round off to 90.

A swimming pool is a rectangular prism. The pool is 36 feet long and 20 feet wide. What is the total amount of water, in cubic f

Sliva [168]

Answer:

$2880\ ft^{3}$

Step-by-step explanation:

The computation of the total amount of water needed could be determined by using the volume formula which is shown below:

$Volume = L \times W \times D$

where

L = length,

W = width,

and D = depth.

Now putting the values to the above formula

$Volume = (36\ ft) \times (20\ ft) \times (4\ ft) \\\\= 2880\ ft^{3}$

Therefore, the total amount of water needed is $2880\ ft^{3}$

We simply applied the above formula

Each week, Alfonso earns $85 for every shift he works at the theater and $15 for every dog-walking job. He uses the expression 8

sesenic [268]

So you didn't put an actual question. To find the money he makes you just plug in the numbers.
If he works 4 shifts at the theater you replace x with 4. Then, you find 85 x 4. You do the same thing with 15y.
