Answer 45
Step-by-step explanation:
Because 2 times 5 is 10 so 7 times 5 is 35 then add them together.
Step-by-step explanation:
<u>Substitute the value of y into the equation;</u>

<u>Add 8 to </u><u>each</u><u> side;</u>
<u>Divide </u><u>each</u><u> side by 8;</u>
Answer:
Its x cause it has no value yet
Step-by-step explanation:
Answer:
Step-by-step explanation:
1st expression: x⁴-y⁴
= (x²)² - (y²)²
= (x² +y²)(x² -y²)
= (x² +y²)(x +y)(x -y)
= (x +y)(x -y)(x² +y²)
2nd expression: x² -y²
= (x +y)(x -y)
3rd expression: x³ -y³
= (x -y)(x² +xy +y²)
Now ,
Lowest Common Multiples (L.C.M.) = common factors * rest factors
= (x+y)(x-y) * (x² +y²)(x² +xy +y²)
= (x² -y²)(x²+y²) * (x² +xy +y²)
= (x⁴ -y⁴)(x² +xy +y²)
