The answer is x+2 b/c
a) whenever it says than it means that this part goes second.
b) a number - substitute w/ any letter
ex: x
c) put it together
two more than (_+2) a number (x) is x+2
Answer:
8f + 4g
Step-by-step explanation:
Given
2(4f + 2g)
Required
Determine the equivalent expression
2(4f + 2g)
Open the bracket
2 * 4f + 2 * 2g
Perform right operations on the above
8f + 4g
<em>The expression cannot be further simplified; Hence the result of </em><em>2(4f + 2g)</em><em> when simplified is </em><em>8f + 4g</em>

Answer:
∠ 5 = 133°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent and supplementary, thus
∠ 1 = 180° - 47° = 133°
∠ 1 and ∠ 5 are corresponding and congruent, thus
∠ 5 = ∠ 1 = 133°
Answer:
See Below
Step-by-step explanation:
A non-homogeneous equation of the form Ax=b always has a solution IF:
The column space of Matrix A has equal "dimensions" and "column length".
Now,
Given, 12 equations and 13 unknown, so Matrix A can be:
Matrix A = 12 x 13
Hence, the column length = 12
Each column here is a vector in space (vector space).
Now, we essentially need to figure out if the columns span the vector space of .
The rank theorem is:
n is 13 so,
Hence,
Rank A = 12
Hence the dimension is 12 and columns span this.
Thus,
Thus the system always has a solution.
