Answer:
-(w-2)=w+2, 8m+4=2(4m-2) Is NOT correct
Step-by-step explanation:
because..... when we multiply -(w-2) we get -w+2. Peter forgot to multiply the negative sign. 8m+4=2(4m-2) is not correct because 2 x 4m is 8m but 2 x 2 is 4 NOT 2 x -2. 2 x -2 is -4.

If log25 ~ 2.3219,
evaluate log280.
Answer:
You need to write log_2 80 in terms of log_2 5 , such that:
log_2 80 = log_2 (8*10)
Using the properties of logarithms, you need to convert the logarithm of product in summation of logarithms, such that:
log_2 (8*10)= log_2 8 + log_2 10
Since log_2 10 = log_2 (2*5) , yields:
log_2 (8*10)= log_2 8 + log_2 (2*5)
log_2 (8*10)= log_2 8 + log_2 2 + log_2 5
You need to write 8 as power of 2, such that:
log_2 (8*10) = log_2 (2^3) + log_2 2 + log_2 5
Using the power property of logarithms, log_a b^c = c*log_a b yields:
log_2 (8*10) = 3log_2 2 + log_2 2 + log_2 5
Since log_2 2 = 1 yields:
log_2 (8*10) = 3 + 1 + 2.3219
log_2 (8*10) = 4 + 2.3219 => log_2 (8*10) = 6.3219
Hence, evaluating the given logarithm , using the indicated properties of logarithms, yields log_2 (8*10) = 6.3219 .
Step-by-step explanation:
The value of [tex]log_2{80}[/tex] if [tex]log_25 = 2.3219[/tex] is 6.3219.
What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.
Given, [tex]log_25 = 2.3219[/tex].
Now, To obtain the value of [tex]log_2{80}[/tex] we'll break it into suitable smaller parts.
Therefore,
[tex]log_2{80} = log_2({8\times10})[/tex].
[tex]log_2{80} = log_28 + log_210[/tex]
[tex]log_2{80} = log_28 + log_2({2\times5})[/tex].
[tex]log_2{80} = log_28 + log_22 + log_25[/tex].
[tex]log_2{80} = 3 + 1 + 2.3219[/tex].
[tex]log_2{80} = 6.3219[/tex].

The solution of a+b>12 is a>−3. What is the value of b?
Answer:
we conclude that when we substitute b = 15, the solution of the inequality becomes:
[tex]a>-3[/tex]
Therefore, the value of b = 15.
The solution graph is also attached.
Step-by-step explanation:
Given the inequality expression
[tex]a+b>12[/tex]
Putting b = 15 in the inequality expression
[tex]a+b>12[/tex]
[tex]a+15>\:12[/tex]
subtract 15 from both sides
[tex]a+15-15>12-15[/tex]
simplify
[tex]a>-3[/tex]
Thus, we conclude that when we substitute b = 15, the solution of the inequality becomes:
[tex]a>-3[/tex]
Therefore, the value of b = 15.
The solution graph is also attached.

3) trapezoid
4) parallelogram
Answer:
2) Square
hope this help
The quadrilateral must have diagonals that are congruent and perpendicular is Square.
What are quadrilaterals?A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.
According to the question
Properties of following for their diagonals are :
Rhombus :
In a rhombus, diagonals bisect each other at right angles.
Diagonals bisect the angles of a rhombus.
Square:
The diagonals of the square bisect each other at 90°
The two diagonals of the square are equal to each other.
Trapezoid:
The length of both the diagonals is equal.
The diagonals of a trapezium always intersect each other.
Parallelogram:
Each diagonal of a parallelogram separates it into two congruent triangles.
The diagonals of a parallelogram bisect each other.
Therefore, according to there properties for their diagonals condition
that quadrilateral must have diagonals that are congruent and perpendicular is satisfied by square only .
Hence, the quadrilateral must have diagonals that are congruent and perpendicular is Square.

You are selling candy bars for a fundraiser. you want to sell at least $200. If snickers cost $2 per bar and M&M's cost $3 per bag, then write an inequality that represents all the possible combinations you can sell to meet your goal.
Answer:
Step-by-step explanation:
Goal = > $2500
Amount raised = $700
Amount needed to raise = $2500 - 700 = $1800
Number of candy bars needed = x
Price of a candy bar = $1.50
1.5x > 1800
x > 1800 ÷ 1.5
x > 1200
Answer: They need to sell more than 1200 candy bars.

Billy is making a sign in the shape of a regular octagon. What is the measure of each interior angle of the sign?
O 45°
O 60°
O 120°
O 135°
Answer:
135°
Step-by-step explanation:
Interior angle= (n-2)/n ×180°
n= no. of sides
so,
putting the value of n which is 8
(8-6)/8 × 180
=135°
The measure of each interior angle of the sign is 135 degrees.
The correct option is D.
What is an interior angle?Angles inside a polygon are referred to as interior angles. A triangle, for instance, has three internal angles. Interior angles are sometimes defined as "angles confined in the interior area of two parallel lines when they are crossed by a transversal."
In a regular octagon, all the interior angles are equal.
The formula to find the measure of each interior angle of a regular polygon with n sides is:
measure of each interior angle = (n-2) x 180 / n
For an octagon, n = 8, so we can substitute this value into the formula and simplify:
measure of each interior angle = (8-2) x 180 / 8
measure of each interior angle = 6 x 180 / 8
the measure of each interior angle = 135 degrees
Therefore, the measure of each interior angle = 135 degrees.
