Answer:
-5w^9.
Step-by-step explanation:
These two terms are what we call, 'like terms'. This means that they are terms whose variables and exponents are the same. 14w^9- 19w^9 have the variable w^9 in common.
In these cases, all we do is use the coefficients (the number in front of the variable). Hence, 14w^9- 19w^9, quite literally turns into, 14-19. If we complete the sum, 14-19= -5. Put it all together, we have -5w^9.
Hope this helps!
Area is just height times width so if it’s a square all sides are equal so you do 3 2/7 time 3 2/7 and get 10.796 in^2
Find the area of the rectangle. 39 times 16=
624-pi (radius squared)
624-3.14 times 8 squared
624- 200.96

Answer:
6
Step-by-step explanation:
We want to expand this; (x + y)⁴
This can be written as;
(x + y)² × (x + y)²
This gives;
(x² + 2xy + y²) × (x² + 2xy + y²)
This gives;
x²(x² + 2xy + y²) + 2xy(x² + 2xy + y²) + y²(x² + 2xy + y²) = x⁴ + 2x³y + x²y² + 2x³y + 4x²y² + 2xy³ + x²y² + 2xy³ + y⁴
Simplifying gives;
x⁴ + 4x³y + 4xy³ + 6x²y² + y⁴
Thus, the coefficient of x²y² is 6
Answer:
$1000 per month
Step-by-step explanation:
5000 dollars is 100 percent so we put 5000 over 100
5000/100
then since we need to find 20 percent of something, we put x over 20
x/20
Then we cross multiply
<u>5000</u> times <u>x </u>
100 20
so 100x = 100000
and x = 1000
Good luck, and hope I did this correctly
