= 9a(5x² + 3x + 2)
The distributive property lets you remove the same factor from all terms and write it outside parentheses.
Answer:
5x + 2 - 2(4x - 2)
Step-by-step explanation:
-2 x 4x= -8x
5x-8x=-3x
-2 x -2= 4
4+2=6
-3x+6
hope this helped ^ ^
Answer:
LCM: 60
HCF: 10
Step-by-step explanation:
Listing Multiples
LCM:
Multiples of 20:
20, 40, 60, 80, 100
Multiples of 30:
30, 60, 90, 120
Therefore,
LCM(20, 30) = 60
----------------------------------------
Factorization
HCF:
The factors of 20 are: 1, 2, 4, 5, 10, 20
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
Then the greatest common factor is 10
Answer:
18.84 square inches
Step-by-step explanation:
Distance across = diameter. The area formula for circles is A= πr. r in here means radius which is 6 inches (half of diameter). π is generally 3.14 or 22/7 depending on the question. multiply the value of π and 6, then you get the answer.
Answer:
<h2>x = 27</h2>
Step-by-step explanation:
BR is parallel to QC therefore ΔBDR and ΔQDC are similar.
The sides are in proportion:
We have
BD = 26 + 39 = 65
QD = 39
RD = 18 + x
CD = x
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 39x from both sides</em>
<em>divide both sides by 26</em>
