Which of the expressions below can be factor using the difference of squares method
Answers
The first thing you can do is look for a subtraction sign. The word difference implies subtraction, so you can rule out any expressions that add terms. Secondly, you can look for squares. 17x^2 - 23y^2 is a subtraction expression, but 17 and 23 are not squares. However, 25x^2 - 64x^2 is a subtraction expression and its terms are squares. 25 = 5x5, 64 = 8x8. Hope this helps!

A rectangle is dilated by a scale factor of 4.
a) The original rectangle is 8 cm by 3 cm. What are the dimensions of the new rectangle?
b) Is the new image a reduction or enlargement? Explain.
HELP PLEASE
Answers
Since the scale factor is 4, we multiply the dimensions of the original rectangle, the preimage, by 4. 8*4 = 32 and 3*4 = 12.
Since the new dimensions are larger than the old dimensions, it is an enlargement.

Factor a GCF from the expression, if possible.
Factor a Trinomial, if possible.
Factor a Difference Between Two Squares as many times as possible.
Factoring completely involves three steps: identifying the GCF, applying the appropriate factoring method, and checking for additional factors. Factoring by grouping is used when there are four terms in an expression and common factors can be factored out separately. An example is given to illustrate the factoring by grouping process.
Explanation:Factoring Completely:Identify the greatest common factor (GCF) of the terms in the expression and factor it out.Apply the difference of squares, trinomial, or grouping method to factor the remaining expression.Check if there are any additional factors that can be factored further.Factoring By Grouping:This technique is used when there are four terms in an expression and there is a common factor between the first two terms and the last two terms. The common factor is factored out separately from the two pairs, and then the resulting binomials are factored further.
Factoring by Grouping Example:Consider the expression 2x + 3y + 4x + 6y. In this case, we can group the terms as (2x + 3y) + (4x + 6y). Common factors can be factored out separately, resulting in (2x + 3y)(1 + 2).

Answers
x=112.5 degrees
.2x=22.5 degrees
(.2x)= 45 degrees
Answer:
x + 5x + 2x = 180
8x = 180
x = 22.5 degrees ( smallest angle), Largest Angle = 112.5 degrees and the third angle = 45 degrees
Let's call the smallest angle x. Then the largest angle is 5x and then the third angle is 2x since it is twice the smallest angle. We know that the sum of all the angles in a triangle is 180 degrees.

28 is 12 less than k
Answers
the value of k is 40.
to solve for k when 28 is 12 less than k, we set up an equation and then solve it.
Let's denote k as the unknown number. According to the problem, 28 is 12 less than k, which can be written as:
28 = k - 12
To solve for k, we need to isolate k on one side of the equation.
28 = k -12
28 + 12 = k
40 = k
k = 40
So, the value of k is 40.
The complete question is:
28 is 12 less than k. 28=12-k Solve for k.

I provided the distance formula and and example for you.
Final answer:
To find the slope between two points, use the formula m = (Y2 - Y1) / (X2 - X1) where (X1, Y1) and (X2, Y2) are the coordinates of the two points. The slopes for the given point sets are: 0, 1, -5/4, and 2.
Explanation:
To find the slope between two points, we can use the formula:
m = (Y2 - Y1) / (X2 - X1)
where (X1, Y1) and (X2, Y2) are the coordinates of the two points.
For the first set of points (5, -5) and (3, -5), the slope is:
m = (-5 - (-5)) / (3 - 5) = 0 / -2 = 0
For the second set of points (2, 3) and (4, 5), the slope is:
m = (5 - 3) / (4 - 2) = 2 / 2 = 1
For the third set of points (-5, 5) and (3, -5), the slope is:
m = (-5 - 5) / (3 - (-5)) = -10 / 8 = -5/4
For the fourth set of points (9, 9) and (12, 15), the slope is:
m = (15 - 9) / (12 - 9) = 6 / 3 = 2

It's 3/5 of the wall is made from brick how do you determine the height of the brick proportion of the wall
Answers
_____
"Of" means "multiplied by", so
(3/5) of the height is brick
means
(3/5)*(the height) = height of brick portion
To find the height of the brick proportion of a wall, multiply the total wall height by the fraction representing the brick portion. For instance, if the wall is 220 cm high and 3/5 is brick, the brick portion's height would be 132 cm.
To determine the height of the brick proportion of the wall, you would need to know the total height of the wall first. Once you have the total height, you can calculate the height of the brick section by multiplying the total height by the fraction of the wall that is brick. For example, if 3/5 of the wall is made from brick, and the wall is 220 cm high, the calculation would be as follows:
Height of brick portion = Total height of the wall × Fraction of wall that is brick
Height of brick portion = 220 cm × (3/5) = 132 cm
Therefore, the height of the brick proportion of the wall would be 132 cm.
