27x^6

(3x^2)^3 = (3^3)(x^2^3) = (27)(x^6) = 27x^6

The expression (4x+5)(3x-7) is the factorization of what trinomial?

RUDIKE [14]

It's easy to find the trinomial. Just multiply (4x + 5) and (3x - 7) together.

$(4x + 5)(3x - 7) = 12x^{2} - 28x + 15x - 35 = 12x^{2} - 13x - 35$

So the final answer is $12x^{2} - 13x - 35$

What is the missing constant term in the perfect square that starts with

Vedmedyk [2.9K]

Answer:

49

Step-by-step explanation:

The expression is given below:

x^2 + 14x

Let y be the constant that will make the expression a perfect square. Therefore, the expression can be written as:

x^2 + 14x + y

Applying the formula b^2 = 4ac, we can easily obtain the value of y as shown below:

x^2 + 14x + y

Coefficient of x^2 (a) = 1

Coefficient of x (b) = 14

Constant (c) = y

b^2 = 4ac

14^2 = 4 x 1 x c

196 = 4c

Divide both side by the coefficient of c i.e 4

c = 196/4

c = 49

Thus, 49 must be added to the expression to make it a perfect square.
