The rule is x10

so 20 is the 4th term of this sequence

200, 2000, 20000,

5th, 6th, 7th,

The 7th term is 20,000

(2y² + 7y + 11) - (8y² - 5y + 7) you can distribute the negative sign to the second expression and then combine the like terms

new expression: (2y² + 7y + 11) (-8y² + 5y - 7)

2y² and -8y² equals -6y²

7y and 5y equals 12y

11 and -7 equals 4

The answer is -6y² + 12y + 4

Solve for a. Show your work (ALL steps must be shown): -2(a-3)=12

irga5000 [103]

Answer

a= -6

Step-by-step explanation:

-2(a-3)=12

1.) -2(a)= -2a

2) -2(-3)= 6

3) -2a+6=12

-6 -6

4) -2a/-2 = 12/-2

a = -6

Two complementary angles are represented by x and x+14 . find the value of x

qaws [65]

Answer:

$x=38\textdegree$

Step-by-step explanation:

Remember that complementary angles <em>always </em>add up to 90°.

We know that the two complementary angles are represented by (x) and (x+14). In other words:

$(x)+(x+14)=90$

So, let's solve for x.

First, combine like terms:

$2x+14=90$

Let's isolate the x by subtracting 14 from both sides:

$(2x+14)-14=(90)-14$

The left cancels. Subtract on the right:

$2x=76$

Divide both sides by 2:

$\frac{2x}{2}=\frac{76}{2}$

The left side cancels. Divide on the right:

$x=38\textdegree$

So, the value of x is 38°.

And we're done!

Answer:

Step-by-step explanation:

Are the sides consistent with the Pythagorean Theorem?

6² + 8² ≟ 9²

36 + 64 ≠ 81, so it is not a right triangle.
