Answer:
25x² - 1
Step-by-step explanation:
Given
(5x + 1)(5x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 1) + 1(5x - 1) ← distribute both parenthesis
= 25x² - 5x + 5x - 1 ← collect like terms
= 25x² - 1

Mai has proven that triangle WYZ is congruent to triangle WYX using Side-Side-Side Triangle Congruence Therom. Why can can she now conclude that diangonal WY bisects angles ZWX and ZYX?
a. Corresponding parts of congruent triangles are congruent.
b. Alternate angles are congruent.
c. This is a quadrilateral.
d. The angles are not congruent.
Since Mai has proven triangles WYZ and WYX to be congruent by the SSS triangle Congruence Theorem, she can conclude that:
Diagonal WY bisects angles ZWX and ZYX because:
all corresponding parts of both triangles are congruent. (Option A).If two triangles are proven to be congruent to each other, it means that all three pairs of corresponding sides and angles of both triangles are congruent and equal to each other.
Thus, since Mai has proven triangles WYZ and WYX to be congruent by the SSS Triangle Congruence Theorem, therefore, all corresponding parts of both triangles are congruent.
If this is so, then Mai can conclude that angles ZWX and ZYX are bisected by diagonal WY. (Option A is correct).

Find the distance from (-3,-1) to (2, 11).
Answer:
13
Step-by-step explanation:
Use the distance formula to find the distance between points
[tex] (x_1, y_1) [/tex] and [tex] (x_2, y_2) [/tex].
Distance formula:
[tex] distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
We have [tex] x_1 = -3, y_1 = -1, x_2 = 2, y_2 = 11 [/tex].
[tex] distance = \sqrt{(2 - (-3))^2 + (11 - (-1))^2} [/tex]
[tex] distance = \sqrt{(2 + 3)^2 + (11 + 1)^2} [/tex]
[tex] distance = \sqrt{5^2 + 12^2} [/tex]
[tex] distance = \sqrt{25 + 144} [/tex]
[tex] distance = \sqrt{169} [/tex]
[tex] distance = 13 [/tex]

You start at (4, 6). You move up 4 units and down 8 units. Where do you end?
Answer:
(4, 2)
Step-by-step explanation:
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (4, 6)
Up 4 units:
(4, 6 + 4) = (4, 10)
Down 8 units:
(4, 10 - 8) = (4, 2)
You end up at point (4, 2)

Letter: 8.5 inches by 11 inches Legal: 8.5 inches by 14 inches Junior legal: 5 inches by 8 inches Tabloid: 11 inches by 17 inches a. Are any of the paper sizes similar? b. The dimensions of government-letter paper are each 0.5 inch less than the dimensions of letter paper. Are these paper sizes similar? Question 2 c. By increasing the shorter side of legal paper by inch, it is similar to the size of junior legal paper.
Answer
a. No none are similar.
b. No.
c. Even if it were to be increased it still won’t be similar as what we would get would be 133 inches.
Step-by-step explanation:
LETTER = 8.5inches * 11 inches = 93.5inches.
LEGAL = 8.5inches * 14 inches = 119 inches
Junior legal: 5 inches * 8 inches = 40inches.
Tabloid: 11 inches * 17 inches = 187 inches
Government paper = 8inches * 10.5 inches = 84 inches.
