Indicate the sum of the terms in each of the following examples, and simplify the result by combining like terms:

katrin [286]

Answer:

The sum of the terms is equal to $5r^2-14r+3s$ .

The value of the sum at $r=1,s=3$ is 0.

Step-by-step explanation:

Given:

The terms that are given are:

$10r^2, -6r, +5s, -8r, +2s, -5r^2, -4s$

The sum of the terms is the addition of the given terms and is given as:

$=10r^2+ (-6r)+5s+ (-8r)+2s + (-5r^2) + (-4s)$

$=10r^2-6r+5s-8r+2s-5r^2-4s$

Now, combining like terms. Like terms means that are of the same type are grouped together. There are 3 different terms here 'r²', 'r' and 's'.

The terms containing 'r²' are: $10r^2, -5r^2$

The terms containing 'r' are: $-8r, -6r$

The terms containing 's' are: $5s, 2s, -4s$

Now, combining the like terms, we get:

$=(10r^2-5r^2)+(-8r-6r)+(5s + 2s -4s)$

$=(10-5)r^2+(-8-6)r+(5+2-4)s$

$=5r^2+(-14)r+3s$

$=5r^2-14r+3s$

Therefore, the final expression is equal to:

$=5r^2-14r+3s$

Now, plug in $r=1,s=3$ . This gives,

$=5(1)^2-14(1)+3(3)$

$=5\times 1-14+9$

$=5-14+9$

$=0$

Therefore, the value of the sum of all the terms at $r=1,s=3$ is 0.

Which sentence describes why polygon MNOP is congruent to polygon JKLP?

bogdanovich [222]

Answer:

Option B.

Polygon JKLP maps to polygon MNOP through a rotation.

Step-by-step explanation:

The picture of the question in the attached figure

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

JK≅MN

KL≅NO

LP≅OP

JP≅MP

and

∠OPM≅∠LPJ

∠NOP≅∠KLP

∠ONM≅∠LKJ

∠NMP≅∠KJP

Polygon JKLP maps to polygon MNOP through a rotation clockwise around point P an angle equal to ∠JPM
