Find the prime factorization of 18 and 27

Mathematics
1 answer:
KengaRu [80]3 years ago
4 0

Answer:

18 = 3*3*2

27 = 3*3*3

Step-by-step explanation:

Prime factorization breaks the number down into factors that are prime

18 = 9*2

Since 9 is not prime we need to break it down again

18 = 9*2= 3*3*2

27 = 3*9  = 3*3*3

<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.

cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft

</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41

Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.

(A) 0.10 feet
(B) 0.05 feet</span>

Use the distributive property to simplify the expression.
zepelin [54]

Option D

Using the distributive property, -7(8x – 3) + x = -55x + 21

<em><u>Solution:</u></em>

Given that we have to use distributive property to simplify the given expression

Given expression is:

-7(8x – 3) + x

Let us first understand about distributive property

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

<em><u>The distributive property is represented as:</u></em>

a(b + c) = ab + ac

Apply this property in given expression for -7(8x - 3)

-7(8x - 3) = (- 7 \times 8x) + (-7 \times -3)\\\\-7(8x - 3) = -56x +21

Apply the above result in given expression

-7(8x - 3) + x = -56x + 21 + x

Combine the like terms. Add -56x and x

-7(8x - 3) + x = -56x + 21 + x = -55x + 21\\\\-7(8x - 3) + x = -55x + 21

Thus the given expression is simplified. Option D is correct

Distribute ^4 to both 2 and q^5

2^4 = 2 x 2 x 2 x 2 = 16
(q^5)^4 = q^20

16(q^20) = 16q^20 

16q^20 is your answer

hope this helps
