Answer:

First expression         8y +4x +10

Second expression    7x-3y +6

If you want to combine both expressions: 5y +11x +16

Step-by-step explanation:

Like terms are the terms which have same variables and powers/roots.

Example: 7x and 2x are like terms because the variables are both "x". So we can combine in 9x

In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same

10y + 3x + 10 + x -2y  

10y-2y=8y          3x+x=4x

so         8y +4x +10

3x - y + 4x + 6 - 2y

3x+4x=7x              -2y -y = -3y

so  7x-3y +6

In rectangle PQRS, PR = 18x – 28 and QS = x + 380. Find the value of x and the length of each diagonal.
Flauer [41]

Diagonals of a rectangle are congruent.


18x - 28 = x + 380


Solving for x, I get 17.


So, x = 17.


PR = 18x - 28


PR = 18(17) - 28


PR = 278


QS = x + 380


QS = 17 + 380


QS = 397

I'm don't understand polygons, as you should know
lawyer [7]

Answer:

540°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, thus

sum = 180° × 3 = 540°

Fofino [41]
We know, length of arc = Ф/360 * 2πr
= 15/360 * (2 * 3.14 * 20)
= 1/24 * (125.6)
= 5.23

In short, Your Answer would be 5.23 Inches

Hope this helps!
