For this case we have the following expression:
(x-5) 1/2 + 5 = 2
Rewriting correctly we have:
(x-5) ^ (1/2) + 5 = 2
Clearing x we have:
(x-5) ^ (1/2) = 2-5
(x-5) ^ (1/2) = -3
(x-5) = root (-3)
x = 5 + i * root (3)
Answer:
The value of x is given by:
x = 5 + i * root (3)
Answer:
EF² = FA²+ EA²
20² = 12² + FA²
400 -144 = FA²
256 =FA²
16cm = FA
Now in Δ DAG
DG² = AG² + DA²
13² = 12 ²+ DA²
169 -144 = DA²
25 = DA²
5cm = DA
Then that means diagonal DF = DA + FA
= 5 + 16
= 21cm

Answer:
8.29
Step-by-step explanation:
49.74 divided by 6 = 8.29
To check: 8.29 x 6 = 49.74
Hope this helped. Feel free to ask questions!
Hi there! BF = 14
If AC = 19, the radius of circle C is 19.
In the picture we can see that AC = A F + CF.
Based on all the data we have we can fill in th: formula:
19 = A F + 12.
Subtract 12 from both sides.
7 = A F
A F = radius circle A = 7
BF, which is the diameter from circle A is two times the radius of the circle. Hence,
BF = 2 × A F = 2 × 7 = 14
~ Hope this helps you.
~ Note: there is a space between A F because the system doesn't accept is without a space (because of rude language).
For question number 2, the answer is A 6x+9
Explanation:
Question Number 19:
So, the correct answer for question number 19 is 6x + 4.
