Answer:

7x + 7y is the product of 7 & (x + y)

Step-by-step explanation:

$7x + 7y = 7(x + y)$

Hence 7 & (x + y) are the factors of 7x + 7y

How do you know if two lines are parallel without a equation?

sesenic [268]

If they do not have solutions (intersections).
If they do not have intersections then they must be parallel. Imagine it on the graph

The measure of <1 = 20x + 21 and the measure of <2 = 30x - 29.

geniusboy [140]

Answer:

Both equal 121 degrees

Step-by-step explanation:

Vertical angles are equal, and and 2 are indeed vertical angles. They are the "top" and "bottom" of the x formed. So you can use this.

angle 1 = angle 2

20x + 21 = 30x - 29

50 = 10x

5 = x

So just plug this in.

20x + 21

20(5) + 21

121

30x - 29

30(5) - 29

121

So both are 121.

Answer:

$x^4 + 4x^3 + 6x^2 + 7x + 2$

Step-by-step explanation:

We are asked to multiply the given polynomials.

$(x^ 2 + 3x + 1) \times (x^2 + x + 2)$

Multiply each term of the first polynomial to each term of the second polynomial.

$x^ 2 \times (x^2 + x + 2) = x^4 + x^3 + 2x^2$

$3x \times (x^2 + x + 2) = 3x^3 + 3x^2 + 6x$

$1 \times (x^2 + x + 2) = x^2 + x + 2$

Add the results

$(x^4 + x^3 + 2x^2) + (3x^3 + 3x^2 + 6x) + ( x^2 + x + 2)$

Combine the like terms

$x^4 + 4x^3 + 6x^2 + 7x + 2$

The answer is written in descending powers of x.
