Answer:

Step-by-step explanation:

Roots of Polynomial:


The small triangle and big triangle are similar - this means they have the same angles. So, if you know the ratio of a side of the big triangle (12) to a side of the small triangle inside it (4), you know the ratio of the other sides. In this case, the side ratio (small to big triangle) is 1/3. Thus, the missing side length is 18/3=6.

Ok so I am gonna help you with this question I hope it helps you okay!
Answer:
Simplifying
4y + 3 = 5x + -7 + 3x + 17
Reorder the terms:
3 + 4y = 5x + -7 + 3x + 17
Reorder the terms:
3 + 4y = -7 + 17 + 5x + 3x
Combine like terms: -7 + 17 = 10
3 + 4y = 10 + 5x + 3x
Combine like terms: 5x + 3x = 8x
3 + 4y = 10 + 8x
Solving
3 + 4y = 10 + 8x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 4y = 10 + -3 + 8x
Combine like terms: 3 + -3 = 0
0 + 4y = 10 + -3 + 8x
4y = 10 + -3 + 8x
Combine like terms: 10 + -3 = 7
4y = 7 + 8x
Divide each side by '4'.
y = 1.75 + 2x
Simplifying
y = 1.75 + 2x
