Celina says true that each of the following expressions is actually a binomial expression.
<h3>What is binomial?</h3>
The binomial is a polynomial of two-term only. For example, x + 5 where x and 5 are the two separate terms.
Celina says that each of the following expressions is actually a binomial in disguise:
a. 5abc - 2a² + 6abc = 11abc - 2a²
The is a binomial expression.
b. 5x³∙2x² - 10x⁴ + 3x⁵ + 3x∙(-2) x⁴ = 7x⁵ - 10x⁴
The is a binomial expression.
c. (t+2)² - 4t = t² + 4
The is a binomial expression.
d. 5(a - 1) - 10(a - 1) + 100(a - 1) = 95a - 95
The is a binomial expression.
e. (2πr - πr² )r - (2πr - πr²)∙2r = -2πr² + πr³
The is a binomial expression.

Answer:
He should have found 8 as the exponent, not –8.
Step-by-step explanation:
im doing a unit test
F ( x ) = tan ( 2 x );
f ` ( x ) = (1 / cos² x )· ( 2 x )` = 2 / cos² x
f` ( π/6 ) = 2 / cos² (π/6) = 2 / (√3/2)² = 2 : 3/4 = 8/3
The answer is 21, blessup my friend stay groovy
To solve, set your equation to your solution.
3x+1=19
Start by subtracting 1 from each side to start isolating the x.
3x+1=19
-1 -1
————-
3x=18
Next, divide both sides by 3 to completely isolate the x.
3x=18
—- ——
3 3
x=6
Therefore, x for f(x)= 19 is 6
You can check by inserting into the equation 3(6)+1=18+1=19.
Hope this helps!!
