Answer:
3.5.
Step-by-step explanation:
3^2 = 9
and 4^2 = 16 so the square root is between 3 and 4.
Take a rectangle 3.4 by 3.6:
the area = 3.4 * 3.6 = 12.24 so an estimate of the square root could be 3.5.
3.5 * 3.5 = 12.25.
Answer:
m=5
Step-by-step explanation:
We can solve this by using a system of equations. The easiest way to solve this is by using substitution.
3m=19-n Subtract both sides by 19 to find n.
<u>-19 -19</u>
3m-19=-n Divide everything by -1 to make n positive.
<u>/-1 /-1</u>
n=-3m+19
Now, we can substitute n into the second equation.
2m+5(-3m+19)=30 Substitute (-3m+19) into n.
2m-15m+95=30 Simplify.
-13m+95=30 Simplify and subtract both sides by 95.
<u>-95 -95</u>
-13m=-65 Divide both sides by -13.
<u>/-13 /-13</u>
m=5
We don't need to solve for n at all, so that is the answer!
Hope this helps, and have an amazing day ♥
Answer:
6(2x - 1)
Step-by-step explanation:
Given
12x - 6 ← factor out common factor of 6 from both terms
= 6(2x - 1) ← in factored form
Answer:
Ummm Lilly Are you the one that I was jus talkin too
Step-by-step explanation:
Answer:
The COMMON RATIO of the sequence is -2.
Step-by-step explanation:
Here, the given sequence is:
5, -10, 20 ,-40
Here, The first term ( a 1 ) of the sequence is (5)
The second term (a 2) of the sequence is (-10)
Third term of sequence (a 3) is 20
Now, calculating the common ratio (r) of sequence ,we get:
So, here r =(-2)
⇒ The COMMON RATIO of the sequence is -2.
Hence, the given sequence in in GEOMETRIC PROGRESSION.
