Answer:

c) 28

explanation :

In this sequence:

a1 = 2

a2 = 4

a3 = 6

a4 = 8

a5 = 10

and so on...

then

the sum from a2 to a5 is:

a2 +a3 + a4 + a5 = 4 + 6 +8 + 10 = 28

<u>Answer</u>:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

<u>Explanation</u>:

BD distance is 4 units

BC distance is 2 units

so in fractions:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

$\sf \dfrac{BC}{BD} = \dfrac{1}{2}$

Suppose that J and K are points on the number line.

rodikova [14]

Answer:

-7, -27

Step-by-step explanation:

J is at -17. K is 10 units from J.

Start at point J, -17:

a) If you go 10 units to the right, you end up at -17 + 10 = -7

b) If you go 10 units to the left, you end up at -17 - 10 = -27

J can be at -7 or at -27

Answer: -7, -27

The hypotenuse of a right triangle measures 16 cm and one of its legs measures 9 cm. Find the measure of the other leg. If neces

Vesnalui [34]

$\sf\huge\underline{\star Solution:-}$

<h3><u>Given that</u>:</h3>

Hypotenuse of a right triangle = $\sf\blue{16cm.}$
One side (leg) = $\sf\blue{9cm.}$

Measure of another side(leg).

<h3><u>Solution</u>:-</h3>

$\rightarrow$ As we know that,

$\sf{A^2 +B^2 \:=\: C^2}$ (Pythagoras Theorem)

So, using this formula we can find measure of another side(leg).

$\rightarrow$ $\sf{A^2 +B^2 \:=\: C^2}$ (putting the value of both given side of triangle)

Here I am putting the value of hypotenuse in C because it is the longest side of triangle.

$\rightarrow$ $\sf{9^2 +B^2 \:=\: 16^2}$

$\rightarrow$ $\sf{81 +B^2 \:=\: 256}$

$\rightarrow$ $\sf{B^2 \:=\: 256-81}$

$\rightarrow$ $\sf{B^2 \:=\: 175}$

$\rightarrow$ $\sf{B \:=\: \sqrt{175}}$

$\rightarrow$ $\sf{B\:=\: 13.22(approx)}$

Therefore, measure of another side (leg) of the triangle = $\sf\purple{ 13.22(approx).}$

Travka [436]

Answer:

a) 4x - 8y

b) 4 × x - 8 × y

c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication

Step-by-step explanation:

a) start with the parentheses

1/3 (6x - 12y)

multiply 6x and -12y by (1/3)

2x - 4y

so now the equation is 5x -3x -4y + 2x -4y

add together the like terms

5x -3x + 2x = 4x

-4y -4y = -8y

so we have 4x - 8y

b) im not good with factored form but i believe this is right

take 4x and separate them by turning it into 4 × x and same for -8y turn it into -8 × y

c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication

im not sure how to prove them equal to the original expression i dont really remember that but i hope this helped
