Answer:
(2n + 7) (2n +7)
Step-by-step explanation:
To solve this problem we need to factorize 4n^2 + 28n +49 as shown below
thus, after factorization we see that first option is correct one
(2n + 7) (2n +7)
we can validate this by expanding it
2n (2n +7) + 7 (2n+7)\
=> 4n^2 + 14n + 14n + 49 = 4n^2 + 28n +49 (which is equal to the problem stated expression)
Answer:
(0, 1/3, 2/3, 1, 1 1/3, 1 2/3, 2)
Step-by-step explanation:
Given :. Length of row = yards
Spacing = 1/3 yard
Startibg point = 0
0 ;
0+1/3 = 1/3
1/3 + 1/3 = 2/3
2/3 + 1/3 = 2/3 = 1
1 + 1/3 = 1 1/3
1 1/3 + 1/3 = 1 2/3
1 2/3 + 1/3
(0, 1/3, 2/3, 1, 1 1/3, 1 2/3, 2)
The angle for shooting laser gun should be 89.98°.
The vertical height where a tiny but horrible alien is standing is given as 443443443 meters. The horizontal distance of a men in black agent from building is given in the question as 181818 meters. So, let us assume the angle formed to be theta (θ).
Writing the formula for tan theta, that relates the given height and distance
Now, tan θ = vertical height ÷ horizontal distance
Keep the values in above mentioned equation of theta to find the angle.
tan θ = 
Performing division to find the tan theta and subsequently calculate the angle
tan θ = 2438.94
θ = tan⁻¹ 2438.94
Calculating tan inverse to find the value of theta
θ = 89.98°
Therefore, the angle for shooting laser gun by a men in black agent should be 89.98°.

Answer:
3x - 6x - 7 = 29 <u>Given</u>
<u>-----------------------------------</u>
3x - 6x -7 = 29
+ 7 + 7 <u>Addition property of equality</u>
3x - 6x = 36
<u>--------------------------------------------------------------</u>
3x - 6x = 36
<u>(</u>3x + -6x) = 36 <u>Combine like terms</u>
-3x = 36
<u>--------------------------------------------------------------</u>
-3x = 36
(-3x = 36)/ -3 <u>Division property of equality</u>
x = -12
<u />
Step-by-step explanation:
I tried to seperate the steps so you can go through them. First you had to add on both sides to take out the like terms, then combine the 3x and the -6x to make -3x (easier to look at and divide), and finally divide to find X. the end product using X cannot be a negative because its a filler space for a real number.
Hope this helps :)

Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
