Answer:

x = - 14, x = - 4

Step-by-step explanation:

Given

(x + 9)² = 25 ( take the square root of both sides )

x + 9 = ± $\sqrt{25}$ = ± 5

Subtract 9 from both sides

x = - 9 ± 5, that is

x = - 9 - 5 = - 14 or x = - 9 + 5 = - 4

What is X? x divided by 4/9 = 9/10

Damm [24]

Answer:

2/5

Step-by-step explanation:

$\frac{x}{\frac{4}{9} } =\frac{9}{10}$

$(\frac{9}{10})(\frac{4}{9} )=\frac{36}{90}$

36 divided by 90 is 2/5.

When solving for X you do the opposite to a number if you are moving it to the other side of the problem. so, since x is being divided by 4/9, 4/9 would be multiplied to the opposite or to the 9/10.

Identify the properties used for the first two steps in simplifying 6ab2 + 4a2b – 3ab2 + 3a2b – 2a2b2.

Kryger [21]

The expression $6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2$ has two similar pairs of conjunctions.

1. Rewrite this expression as
$6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2=$
$=(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2$
and then
2. add the similar conjunctions

 $(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2=3ab^2+7a^2b-2a^2b^2$ .

The pattern 2, 5, 17, ________, ________ follows the rule multiply by 4, then subtract 3. What are the next two terms?

vitfil [10]

Answer:

None of the answer choices.

Step-by-step explanation:

The pattern to this problem is multiply by 4, and subtract 3. However when doing 17 * 4, you get 68. Look how both of the answer chouces start with 68, and we haven't even subtracted 3 yet. This shows that the answer choices are wrong.

Correct Answer: 65, 257
