Answer:

A. The first five terms in Pattern A are 2, 7, 12, 17, 22.

Step-by-step explanation:

I will just write out the first five terms for both patterns so it is easier to see.

Pattern A: 2, 7, 12, 17, 22

Pattern B: 2, 5, 9, 12, 15

C and D are both false. B is also false because it adds 4 from 5 to 9 instead of 3. "A" is the correct answer since it matches the correct terms.

Answer:

A. The first five terms in Pattern A are 2, 7, 12, 17, 22

Step-by-step explanation:

Pattern A

Start at 2 and follow the rule "add 5"

$\sf 2 \underset{+5}{\longrightarrow} 7 \underset{+5}{\longrightarrow} 12 \underset{+5}{\longrightarrow} 17 \underset{+5}{\longrightarrow} 22$

So the first five terms in Pattern A are 2, 7, 12, 17, 22

Pattern B

Start at 2 and follow the rule "add 3"

$\sf 2 \underset{+3}{\longrightarrow} 5 \underset{+3}{\longrightarrow} 8 \underset{+3}{\longrightarrow} 11 \underset{+3}{\longrightarrow} 14$

So the first five terms in Pattern B are 2, 5, 8, 11, 14

True Statement

Therefore, the statement that is true is:

A. The first five terms in Pattern A are 2, 7, 12, 17, 22

Write a list of steps that are needed to find the measure of angle B if angle A is 72 and angle C is 113 ( the figure is a trian

Nuetrik [128]

Triangle has 3 angles, A, B, C. The total interior angle of a triangle is 180.
180 = A + B + C
180 = 72 + B + 113
180 = B + 185
B = 180 - 185
B = -5

This only proves that the figure is not a triangle because angle B is negative.

I WILL MARK BRAINLIEST

vagabundo [1.1K]

Answer:

$\frac{81}{m^7}$

Step-by-step explanation:

We have a certain expression and are asked to find its equivalent with the answers provided :

$(3m^{-4} )^3(3m^5)$

Remove the parenthesis around 3m^5 :

$(3m^{-4} )^3*3m^5$

Do the exponent rule for outside and inside exponent parenthesis :

$(3m^{-4*3} )$

$3^3m^{-12} *3m^5$

Apply addition exponent rule :

$m^{-12} *3^{3+1} m^5$

Add :

$m^{-12} *3^4m^5$

Apply the addition rule for -12 + 5 :

$3^{4} m^{-7}$

Apply negative exponent rule for m^-7 :

$3^4*\frac{1}{m^7}$

Multiply the fractions :

$\frac{1*3^4}{m^7}$

$\frac{81}{m^7}$

The length of a rectangular flower garden is 9 feet and it’s width is 5 feet how many feet of fencing will be needed

Tju [1.3M]

Use the simple perimeter formula.
P = 2L + 2W
P = 2(9) + 2(5)
P = 19 + 10
P = 29ft

Therefore 29ft of fencing will be needed.

Drag the choices into the boxes to explain how all real numbers have a decimal expansion.

KATRIN_1 [288]

The decimal forms of some real numbers, like( 3/16), terminate, while the decimal forms of other real numbers, like(4 2/11 ), do not terminate, but have a repeating pattern. Still, other real numbers, like(5 squared ), have decimal forms that neither terminate nor repeat.

Step-by-step explanation:

1. The decimal forms of some real numbers, like( ), terminate

A number is terminating if it has decimal with finite number

So, $\frac{3}{16}= 0.1875$ as decimal stops after 4 digits so it is terminating.

2. the decimal forms of other real numbers, like( ), do not terminate, but have a repeating pattern.

A number that do not terminate, but have a repeating pattern.

So, $4 \frac{2}{11} =\frac{44}{11}=4.1818181$

3. have decimal forms that neither terminate nor repeat

5^2 = 25 it neither terminates nor repeat

So, answers will be:
