Which expression is a difference of squares with a factor of 5x − 8?

Mathematics

Olegator [25]3 years ago

Answer:

25x^2-64

Step-by-step explanation:

Remember that the formula for the difference of squares is a^2-b^2=(a+b)(a-b). The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:

(5x-8)(5x+8)=(5x)^2-8^2

(5x-8)(5x+8)=5^2x^2-64

(5x-8)(5x+8)=25x^2-64

We can conclude that the correct answer is 25x^2-64.

Which relationship in the triangle must be true?
Paul [167]

We'll assume this is an arbitrary triangle ABC.


A) No, the sines of two different angles can be whatever they want


B) sin(B)=cos(90-B)


Yes, that's always true. The "co" in cosine means "complementary" as in the complementary angle, which adds to 90. So the sine of an angle is the cosine of the complementary angle.


C) No, the correct identity is sin(180-B)=sin B. Supplementary angles share the same sine.


D) Just like A, different triangle angles often have different cosines.


Answer: Choice B

Can someone please help me with this???
tino4ka555 [31]

Answer:

1 cm

Step-by-step explanation:

To solve this problem we can use the Pythagorean theorem. In fact the diagonal of a rectangle is an hypotenuse of a right triangle, while the length is a leg. The width is the other leg

width = √2^2 - (√3)^2 = √4 - 3 = √1 = 1 cm

you pay 3.3 cents per minute for long-distance phone calls on your phone. your phone bill is $3.40 write and solve an equation t
MaRussiya [10]
If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:

3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes 

The correct result would be <span>103.03 minutes.</span>
