If we observe closely the given, we can note that the
terms given are perfect cubes. That is,
<span> x^3 is
cube of x and</span>
<span> 343 is
cube of 7</span>
Hence, the expression is the sum of two cubes. For the
sum of cubes, we follow the following rule for the factoring:
<span> a^3 + b^3 = (a +
b)(a^2 – ab + b^2)</span>
Applying the rule to the given, the factors would be:
<span> X^3 + 373 = (x +
7)(x^2 – 7x + 49)</span>
Answer:
8 feet
Step-by-step explanation:
you use pythagoras so you do 6² + 4² =52. then you square root 52 which is 7.2 so she needs 8 feet.
The answer would be 80 degrees. Brainliest answer? :3
write an expression that can be used to find the nth term for each sequence listed below.7, 13, 19, 25, 31,.... -1,2,5,8,11,14

You'll have to use an arithmetic sequence to find the nth term. Use the equation a=6n+1
Answer:
-4x-31
Step-by-step explanation:
1) Distribute:
(-13x-15)+(9x-16)
2) Eliminate parenthesis that are not useful:
-13x-15+9x-16
3) Subtract the numbers:
-13x-31+9x
4) Combine like terms:
-4x-31
Hope this helped!
