The perimeter would be 39 feet. The area would be 360 feet. I'm not sure which will be appropriate for this question (you decide).
Elga's age is 50, and Alvin's age is 56. So, the sum of their ages is 106.
Answer:
<h2>A. y = -9x - 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em> - slope
<em>b</em> - y-intercept (0, b)
We have the slope <em>m = -9</em> and the y-intercept (0, -2) → <em>b = -2</em>.
Substitute:
<em>y = -9x + (-2) = -9x - 2</em>
Answer:
A + 8 = c
Or
A = c - 8
Step-by-step explanation:
Given a = b + 12 we can substitute that in for
b = c + 4.
a + 12 = c + 4
This means
A + 8 = c
Or
A = c - 8
