The triangles are propotional

Step-by-step explanation:

FH = 45 = 5

BC 27 3

GH = 22.5 = 5

BD 13.5 3

GF = 30 = 10 = 5

X/3 = 8 3 divided by x = 8 what’s the x?

anzhelika [568]

Answer:

x=24

Step-by-step explanation:

1. Multiply all terms by the same value to eliminate fraction denominators

x/3=8

3(x/3)=8(3)

2. Cancel multipled terms that are in the same denminator

3(x/3)=8(3)

x=3(8)

3. Multiply the numbers

x=3(8)

x=24

what is the sum of a 7-term geometric series if the first term is negative 11 the last turn is -45056 and the common ratio is -4

patriot [66]

For a geometric sequence with common ratio $r$ , we have

$a_n=a_{n-1}r$

that is, the $n$ -th term in the sequence is the product of the previous term and the common ratio $r$ . So

$a_n=a_{n-1}r=a_{n-2}r^2=\cdots=a_1r^{n-1}$

Then the sum of the first 7 terms is

$S_7=\displaystyle\sum_{n=1}^7a_n=a_1+a_2+\cdots+a_7$
$\implies S_7=a_1+a_1r+\cdots+a_1r^6$

Notice that

$S_7r=a_1r+a_1r^2+\cdots+a_1r^7$

so we can subtract this modified sum from $S_7$ to get

$S_7-S_7r=S_7(1-r)=a_1-a_1r^7\implies S_7=a_1\dfrac{1-r^7}{1-r}$

We're told that $a_1=-11$ and $r=-4$ , so the sum of the first 7 terms is

$S_7=(-11)\dfrac{1-(-4)^7}{1-(-4)}=144,188$

Fill in the blank.

The correct answer is: Commutative Property

Further Explanation:

The commutative property states that the order of number doesn't matter and changing the order of numbers or variables will produce the same result.

Commutative Property of Addition:

The Commutative Property of addition means that an expression can be written as a + b = b + a.

Commutative Property of Multiplication:

The Commutative Property of multiplication means that an expression can be written as a • b = b • a

Hence, the correct answer is: Commutative Property

Keywords: Commutative property, addition, multiplication
