Well to do this, we need to know the least common multiple (LCM) of 6 and 8. Lets list the factors out.

6, 12, 18, 24, 30, 36
8, 16, 24, 32, 40, 48

As we can see, the least common multiple of 6 and 8 is 24.

Now we know that there are 8 plates per package and 8 goes into 24 3 times, so naturally Shaniya needs 3 packages of plates

Hope this helped!!! :)

Find the total area the regular pyramid.<br><br> T.A. =

m_a_m_a [10]

Answer:

20 +4√2

Step-by-step explanation:

Find the total area the regular pyramid = A + 1/2ps

A is the Base area

p is the perimeter of the base

s is slant height

A = 1/2 * 4 * 4

A = 16/2

A = 8

p = 4 + 4 + (√4^2+4^2)

p = 8 + √32

p = 8 + 4√2

s = 4

Substitute

TSA = 8 + 8 + 4√2 + 4

TSA = 20 +4√2

Hence the total surface area is 20 +4√2

Find the first three terms of the series represented by the formula 3(- 2)(n - 1).

enyata [817]

Answer:

0, - 6, - 12

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the formula

a₁ = 3(- 2)(1 - 1) = 3 × - 2 × 0 = 0

a₂ = 3(- 2)(2 - 1) = 3 × - 2 × 1 = - 6

a₃ = 3(- 2)(3 - 1) = 3 × - 2 × 2 = - 12

First 3 terms are 0, - 6, - 12

Answer:

$\sf x =\dfrac{2}{3}$

Explanation:

$\sf \rightarrow \dfrac{x+1}{2} = \dfrac{7x-3}{2}$

cross multiply

$\sf \rightarrow 2(x+1) = 2(7x-3)$

divide both sides by 2

$\sf \rightarrow x + 1 = 7x-3$

isolate variables

$\sf \rightarrow x -7x = -3-1$

simplify

$\sf \rightarrow -6x = -4$

divide both sides by -6

$\sf \rightarrow \dfrac{-6x}{-6} = \dfrac{-4}{-6}$

simplify

$\sf \rightarrow x =\dfrac{2}{3}$

When they say solve the product in the lowest terms what do they mean?

m_a_m_a [10]

when people say " in lowest terms" they usually mean like the simplified version of an answer

an example of this would be like

make $\frac{2}{4}$ into lowest terms

the answer would be $\frac{1}{2}$

if you dont understand comment on this and ill try to break it down more

Answer:

<h2>D. (42 - 2x)(32 - 2x) = 900</h2>

Step-by-step explanation:

<em>Look at the picture.</em>

The dimensions of the picture:

(42 - 2x)in × (32 -2x)in

The formula of an area of a rectangle:

A = l · w

l - length, w - width

Substitute l = (42 - 2x), w = (32 - 2x) and A = 900

(42 - 2x)(32 - 2x) = 900
