Step-by-step explanation:

The expression that could represent the length of one side of the square is; [tex]4x^2y^4[/tex].

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol it can also be used to indicate the logical syntax's order of operations and other features.

Given that;

The area of the square A  = [tex]16x^4y^8[/tex]

Consider that a is the side length of the square

The area of the square is given by;

[tex]\Rightarrow A=(\text{side length})^2[/tex]

So, we can write the expression as;

[tex]\Rightarrow a^2=16x^4y^8\\\\\Rightarrow a=4x^2y^4[/tex]

Hence, the length of each side is 4x^2y^4

Answer: (t,u) -> (t-3, u+8)

Step-by-step explanation: Up is the y value and left is the x value.

In the point ( t,u) t is the x value and u is the y value.

Moving to the left, you subtract the value and moving up you add the value.

The answer would be (t, u) → (-t – 3, u + 8)

1 = Given

2 = Given

3 = Substitution Property

4 = Distributive Property

5 = Given

6 = Substitution Property

7 = Simplify

8 = Subtraction Property

9 = Addition Property

By substituting given c and d values inn the given equation and simplifying we get a=b. Hence, proved.

Given that, 2c =d-2b, c = a-b and d= a + b.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

To prove: d=a+b

Proof:

1. 2c =d-2b (Given)

2. c=a-b (Given)

3. 2(a-b)=d-2b (Substitute c=a-b)

4. 2a-2b=d-2b

5. d=a+b (Given)

6. 2a-2b=a+b-2b (Substitute d=a+b)

7. 2a-2b=a-b

8. a-2b=-b (Transpose a to LHS and simplify)

9. a=b (Transpose a to RHS and simplify)

By substituting given c and d values inn the given equation and simplifying we get a=b. Hence, proved.

Answer:

..............................................................................................................

Step-by-step explanation:

The value of x=2 and y=1.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x+2y=8

5x+2y=12

Now, solving both using method of Elimination Method

3x - 5x = 8-12

-2x= -4

x = -4/ -2

x= 2

and, 3x+ 2y = 8

3(2) + 2y = 8

6  + 2y = 8

2y = 8-6

2y = 2

y = 2/2

y= 1

Hence, the value of x=2 and y=1.

Answer: (-5,1)

Step-by-step explanation: Explanation in picture.

This is because 65/13 = 5 when using a calculator or long division. There are no fractional or decimal parts to the result 5, so 5 is an integer.

Something like 86/6 = 14.333 approximately showing the result is not an integer. The same applies to choice C and choice D as well.

Answer:

1.84

Step-by-step explanation:

25.38-23.54

Given:

Consider the below figure attached with this question.

[tex]m\angle 3=(x+30)^\circ[/tex] and [tex]m\angle 4=(2x-80)^\circ[/tex].

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

[tex]m\angle 3=m\angle 4[/tex]

[tex](x+30)^\circ=(2x-80)^\circ[/tex]

[tex]x+30=2x-80[/tex]

[tex]x-2x=-30-80[/tex]

[tex]-x=-110[/tex]

[tex]x=110[/tex]

Now,

[tex]m\angle 3=(110+30)^\circ[/tex]

[tex]m\angle 3=140^\circ[/tex]

Therefore, the measure of angle 3 is 140 degrees.
