Answer:

(-4x - 2)(-5x) + (-4x - 2)(3)

Step-by-step explanation:

Your polynomial is

(-4x - 2)(-5x + 3)

The distributive property states that

a(b + c) = ab + ac

Let a = -4x - 2. Then

(-4x - 2)(-5x + 3) = a(5x + 3) = a(-5x) + a(3)

Substitute the value of a.

a(-5x) + a(3) = (-4x - 2)(-5x) + (-4x - 2)(3)

You have just distributed the first binomial (-4x - 2) among the terms of the second binomial.

Y = x² + 5x +4 Factor

Answer:

(x + 1)(x + 4)

Step-by-step explanation:

We want to factor x² + 5x +4 into two binomial factors. Note that 1*4 = 4 and that 1 + 4 = 5, so:

y = x² + 5x +4 = (x + 1)(x + 4)

What is the value of x? Enter your answer in the box.

Art [367]

Answer:

46 degrees

Step-by-step explanation:

you know that if you add 134 and x it will equal a straight line or 180 degrees. So set it up as an addition problem.

134 + x =180 subt. 134 from both sides

x=180-134

x=46 degrees

Find x (7x-11) (2x-3) (5x-2)

Tomtit [17]

Answer:

x = 14

Step-by-step explanation:

Total angle measure of a triangle - 180°

Add all the angles together and make them equal to 180.

Solve for x.

7x - 11 + 5x - 2 + 2x - 3 = 180

14x - 16 = 180

14x - 16 + 16 = 180 + 16

14x = 196

$\frac{14x}{14} = \frac{196}{14}$

x = 14
