Factorization:

Answers

Answer:

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

Step-by-step explanation:

4x^2 + 3x - 10

4 * 10 = -40

We need 2 numbers whose product is -40 and whose sum is +3.

Theses are = - 5 and + 8.

So we write:

4x^2 + 8x + -5x - 10

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

= (4x - 5)(x + 2).

Factor 20x2 + 25x - 12x - 15 by grouping.

Answers

Answer:

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

step-by-step explanation:

20x^2 + 25x - 12x - 15 by grouping:

Start with the expression:

20x^2 + 25x - 12x - 15.

Group the terms in pairs, like this:

(20x^2 + 25x) - (12x + 15).

Now, look for the greatest common factor (GCF) in each group:

In the first group
(20x^2 + 25x), the GCF is 5x because both terms are divisible by 5x.

So, factor out 5x: 5x(4x + 5).

In the second group (12x + 15), the GCF is 3 because both terms are divisible by 3.

So, factor out 3: 3(4x + 5).

Now, your expression looks like this:

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

Notice that both groups have the common factor (4x + 5).

Factor this out: (4x + 5)(5x - 3).

So, the factored form of 20x^2 + 25x - 12x - 15 is (4x + 5)(5x - 3)

Find the angle between the given vectors to the nearest tenth of a degree.u = <-5, -4>, v = <-4, -3>

Answers

The question ask to find the angle between the given vector to the nearest tenth of a degree and base on the value or the coordinates of each vector, the possible value of the angle base on the said vectors is 1.8 degree. I hope you are satisfied with my answer and feel free to ask for more 

Answer:Hence, the angle between the given vectors is 1.8°.

Step-by-step explanation:

Since we have given that

\vec{u}=-5\hat{i}-4\hat{j}\n\vec{v}=-4\hat{i}-3\hat{j}

We need to find the angle between the given vectors:

\cos\theta=\frac{\vec{u}.\vec{v}}{\mid\vec{u}\mid.\mid \vec{v}\mid}\n\n\cos \theta=\frac{(-5\hat{i}-4\hat{j}).-4\hat{i}-3\hat{j}}{√((-5)^2+(-4)^2)√((-4)^2+(-3)^2)}\n\n\cos \theta=(20+12)/(√(41)√(25))\n\n\cos \theta=(32)/(5√(41))\n\n\theta=\cos^(-1)(0.99)\n\n\theta=1.78^\circ

Hence, the angle between the given vectors is 1.8°.
