Answer:

See photo.

Step-by-step explanation:

First, you need to find an already complete row, column, or diagonal and find its sum. This is the value that every other row, column, and diagonal needs to add up to. Next, find one that has two values filled in. Add these two numbers. Subtract them from the sum. The number you get is what needs to be in open box of that row/column/diagonal. Then you'll have another with two values, and you do the same thing for that one, and continue.

Example: 0+7+2= 9 so the sum for the left one is 9. you have a column with a 7 and a 3. 7+3= 10. 9-10= -1. then look at the diagonal. you have 2 and 3. 2+3=5, 9-5=4 so 4 is that one. and so on.

Which algebraic expression represents the following: the sum of four times a number and six? (1 point) 4x + 6

jeka94

The algebraic expression of the statement is 4x + 6

<h3>How to determine the algebraic expression?</h3>

The statement is given as:

The sum of four times a number and six

Rewrite as:

The sum of 4 times a number and 6

Let the number be x

So, we have

The sum of 4 times x and 6

Evaluate the product

The sum of 4x and 6

Evaluate the sum

4x + 6

Hence, the algebraic expression of the statement is 4x + 6

A box with a square base and open top must have a volume of 4,000 cm3. Find the dimensions of the box that minimize the amount o

Marysya12 [62]

Let the side of the square base be x, and the height of the box be h.

The material of the base is x^2, and the material of the four sides is 4xh. 

4000 = hx^2 
h = 4000/x^2 

The total material is 

M = x^2 + 4x(4000/x^2) = x^2 + 16000/x 

Take the first derivative of M and set equal to 0. 

M' = 2x - 16000/x^2 = 0 

Multiply by x^2: 

2x^3 = 16000 
x^3 = 8000 
x = 20; h = 10; M = 1200

How to simplify 182/39

adell [148]

182/39
182/39 = improper fraction

182 ÷ 39 = 4.6...
39 × 4= 156
182 - 156 = 26

4 = whole number
26 = numerator
39 = denominator

4 26/39

This ^^ is how you simplify 182/39.

182/39 = 4 26/39.

182/39 in simplest form is 4 26/39
