Help please Geometry test

Mathematics
1 answer:
ahrayia [7]3 years ago
6 0

Step-by-step explanation:

To find x,

21x - 9 = 117

21x = 126

x = 6

To find arc AB,

21(6) - 9 = 117

To find Arc AE,

117 + x = 180

x = 63

Arc ABC,

117 + 63 = 180

ACE

180 + 27 + 90 = 297

Which expressions are completely factored?
amm1812

The only expressions that are correctly factored are;

A) 16a⁵ - 20a³ = 4a³(4a² - 5)

B) 24a⁴ + 18 = 6(4a⁴ + 3)

C) 12a³  + 8a = 4a(3a² + 2)

D) 30a⁶ - 24a² = 3a²(10a⁴ - 8)

<h3>How to factorize equations?</h3>

1) 16a⁵ - 20a³

To factorize this, we will have to get out the common factor first. The common factor is 4a³. Thus, we now have;

4a³(4a² - 5)

2) 24a⁴ + 18

To factorize this, we will have to get out the common factor first. The common factor is 6. Thus, we now have;

6(4a⁴ + 3)

3) 12a³  + 8a

To factorize this, we will have to get out the common factor first. The common factor is 4a. Thus, we now have;

4a(3a² + 2)

4) 30a⁶ - 24a²

To factorize this, we will have to get out the common factor first. The common factor is 3a². Thus, we now have;

3a²(10a⁴ - 8)

Will give brainlist plz help its for my 9 week exam<br><br> a. 228<br> b. 229<br> c. 172<br> d. 171
natka813 [3]

Answer:

I think its 229

if you take how many yellow marbles he got out of 7 it would be 3/7 and then I divided 400 by 7 and got 57. something so I multiplied 3 times 57 and got 171. So if you take 400-171 you get 229

The quadrilaterals ABCD and JKLM are similar.
Paha777 [63]

Answer: 4.8

Step-by-step explanation:

Corresponding sides of similar figures are proportional, so

\frac{x}[4}=\frac{6}[5}\\\\x=4\left(\frac{6}{5} \right)=\boxed{4.8}
