Answer:
If the two side planks are equal lengths then the answer is 26 1/3.
Answer:
-4
Step-by-step explanation:
We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:
y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1
y - (-7) = 3(x-(-1))
y+7 = 3(x+1)
y+7 = 3x +3
Change to slope-intercept form:
y = 3x + 3 - 7
y = 3x = -4
the y intercept is -4

The Domain also known as the x value would be (-2,1,0,3)
Answer:
2x-30 + x + 40 = 180
3x + 10 = 180
3x = 170
x = 56
