Answer:

x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

80 - x = 90 - 2x

x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.

Write the sum as a product of two factors 25g+10+5<br><br>

agasfer [191]

Answer:

$5\times(5g+2f+1)$

Step-by-step explanation:

$25g+10f+5$

Writing each term in its factors:

$(5\times5)g+(5\times2)f+5$

We find out that 5 is the GCF of all the terms

Factoring out 5 from the given expression.

$5\times(5g+2f+1)$

Factors: 5 and $(5g+2f+1)$

Thus:

$25g+10f+5 = 5\times(5g+2f+1)$
