Answer:
B
Step-by-step explanation:
When a number is in front of the parethese, it is multiplying all the terms inside of it.
Looking at the first answer, the 2 multiplies 2/5x and 2, getting 4/5x + 4. This is not equivllent to 2 2/5x +1.
In the next one 2 is multiplying the same values, and results in 4/5x + 4. This is indeed equivelent to 4/5x + 4.
So this is your answer.
Hope this helps!
Answer: x^8 - y^8
Step-by-step explanation: x^8 - y^8
using a^2 - b^2 = ( a + b )( a - b )
( x^4 + y^4 )( x^4 - y^4 )
( x ^4 + y^4 )( x^2 + y^2 )( x^2 - y^2 )
( x^4 + y^4 )( x^2 + y^2 )( x + y )( x - y )
x = 7.5° and y = 75°
Solution:
ΔMNO is equilateral triangle.
<em>Each angle in equilateral triangle is 60°.</em>
⇒ m∠MNO = 60°
⇒ 2x° + 4x° + 2x° = 60°
⇒ 8x° = 60°
Divide by 8 on both sides.
⇒ x° = 7.5°
In the 2 triangles which contain NM , NO and angles 2x° , 2x°
MN = ON ⇒ equilateral triangle
∵ 2x° = 2x° = 15°
m∠M = m∠O = 60° ⇒ equilateral triangle
∴ The two triangles are congruent.
The third angles in the two triangles are equal and their measure is
180 – (60 + 15) = 105°
105 + y° = 180 ⇒ straight angle
y° = 180 – 105 = 75°
y° = 75°
Hence x = 7.5° and y = 75°.
44 boots were sold all together. To figure this out first you need to find how many of the other boots there were. 8 rugby boots and 12 hiking boots. 8 + 12 + 24 = 44.
