Answer:

8x^36

Step-by-step explanation:

first term (a) = $8x^{8}$

Second term (t2)= $8x^{12}$

common ratio (r)

= $\frac{8x^{12} }{8x^{8} }$

= $x^{4}$

now the 8th term of the G.S is

t8 = $ar^{n-1}$

= $8x^8 * (x^4)^8^-^1$

= $8x^8 * (x^4)^7\\$

= $8x^8 *x^2^8\\= 8x^3^6$

hope it will help

Yan is climbing down a ladder. Each time he descends four rungs on the ladder, he stops to see how much farther he has to go

anastassius [24]

Question:

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?

4+4+4+4

8+8+8+8

(-1)(4+4+4+4)

(-8) + (-8) + (-8) + (-8)

Answer:

$Total = (-8) +(-8) +(-8) +(-8)$

Step-by-step explanation:

Given

$Rungs = -4$ --- It is negative because he is climbing down

$Steps = 8$

Required

An expression for the number of rungs climbed

To do this, we simply multiply the number of rungs by the steps taken.

$Total = Rungs * Steps$

$Total = -4 * 8$

This can be rewritten as:

$Total = -8 * 4$

The product, when written as sum is:

$Total = (-8) +(-8) +(-8) +(-8)$

X-y=-3 Anyone know how to do this ?

horsena [70]

X - y = -3

Move constant to the left by adding its opposite to both sides

x - y + 3 = -3 + 3

The sum of two opposites equals

your answer would be: x - y + 3 = 0

6x - y^2 +3x; if x = 4, y = 7, z = 10

uysha [10]

Answer:

Step-by-step explanation:

x = 4

y = 7

z = 10

6x - y^2 + 3z

= 6 ( 4 ) - 7^2 + 3 ( 10 )

= 24 - 49 + 30

= 24 + 30 - 49

= 54 - 49

= 5
