24 cm²
easy way to find surface area of a cube.
use the formula: 6a²
[tex]\hookrightarrow 6(2)^2[/tex]
[tex]\hookrightarrow 6(4)[/tex]
[tex]\hookrightarrow24[/tex]
We know that:
[tex]\space\ Surface \space\ area \space\ of \space\ cube=\s Area \space\ of \space\ it's \space\ faces[/tex]
This means that:
[tex]\space\ Surface \space\ area = [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)][/tex]
Simplify the expression to find the surface area.
Simplifying the expression:
[tex][(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] \\\\\ [4] + [4] + [4] + [4] + [4] + [4]\\\\ 4[6] \\\\ 24 \space\ cm^{2}[/tex]
Hence, the surface area is 24 cm².

It takes Krys and Glen 1_4hour to walk a mile. This week Krys walked 9 miles and Glen walked 3 miles. How much longer did Krys walk than Glen?
Answers
Answer:
Krys walked 1 1/2 hours longer than Glen.
Step-by-step explanation:
Glen walked 3 miles
3 x 1/4 = 3/4
Krys walked 9 miles
9 x 1/4 = 9/4
9/4 - 3/4 = 6/4
6/4 = 1 2/4
1 2/4 = 1 1/2

Step-by-step explanation:
You want the simplified form of the rational expression ...
[tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8}[/tex]
SimplificationWe simplify this by combining terms over a common denominator, then cancelling any common factors from numerator and denominator.
[tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8} = \dfrac{(x-2)}{(x-4)(x-2)}-\dfrac{2}{(x-4)(x-2)}\\\\\\=\dfrac{(x-2)-2}{(x-4)(x-2)}=\dfrac{x-4}{(x-4)(x-2)}=\boxed{\dfrac{1}{x-2}}[/tex]
Note that the domain still excludes x=4, in addition to the obvious exclusion of x=2.

What is the slope of the line?
Answers
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".
Step-by-step explanation:
Steps for Graphing a Line With a Given Slope
Plot a point on the y-axis. (In the next lesson, Graphing with Slope Intercept Form, you will learn the exact point that needs to be plotted first. For right now, we are only focusing on slope.)Look at the numerator of the slope. Count the rise from the point that you plotted. If the slope is positive, count up and if the slope is negative, count down.
Look at the denominator of the slope. Count the run to the right.
Plot your point.
Repeat the above steps from your second point to plot a third point if you wish.
Draw a straight line through your points.

Which is the best statement of the angle-angle similarity theorem?
A. When the preimage of a triangle is a dilation of the image, the triangles are similar.
When triangles have two pairs of corresponding angles that are congruent, the third pair of angles is also congruent.
B. When triangles have two pairs of corresponding angles that are congruent, those triangles are similar.
C. When the interior angles of a polygon sum to 180 degrees that polygon is a triangle.
Answers
The best statement of the angle-angle similarity theorem is (a) When the preimage of a triangle is a dilation of the image, the triangles are similar.
How to determine the similarity statement?The angle-angle similarity theorem is used in similar triangles; especially when a triangle is dilated (i.e. resized) to form another triangle
When triangles are dilated, the corresponding angles in both triangles (i.e. the image and the pre-image) are always equal
Hence, the best statement of the angle-angle similarity theorem is (a)

Are the numbers of white and yellow flowers in Cara’s arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
Yes; y=35w
Yes; y=53w
No; y=3w+5w
No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector’s arrangements proportional?
Which equation relates the number of white flowers, h, to the number of yellow flowers, e?
Yes; e=32h
Yes; e=23h
No; e=h+2
No; e=h−2
Answers
Answer:
A.
1. no, y = 5 + 3w
B.
no, e = h + 2
Step-by-step explanation:
Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.
Clara's arrangement :
White (w)Yellow (y)Testing if relationship is proportional :
y = kw5 = 3k
[tex] k = \frac{5}{3}[/tex]
Yes, the relationship is proportional [tex] y = \frac{5}{3}w[/tex]
Hector's arrangement :
White (h)Yellow (e)The number of yellow flowers surpasses the number of white flowers by a constant value of 2.
Hence, the relationship can be modeled thus ;
e = h + 2Therefore, the relationship is not proportional.
