Answer:6x+126in^2
Step-by-step explanation:
a =15 long
b=x. Wide
A=ax
A=15x represenrs picture area
Add on each side of picture 3 in
a1=15+6=21 in
b1=x+6
Calculate area
A1=a1b1
A1=21(x+6)
Area of frame = A1-A
Area of frame=21(x+6)-15x=21x-15x+126=6x+126in^2
Answer:
The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
In our case, we are given
The slope m = -1/2
Point (2, -3)
now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept
-3 = -1/2(2) + b
-3 = -1 + b
b = -3 + 1
b = -2
now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation
y = mx + b
y = -1/2x + (-2)
y = -1/2x - 2
Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Answer:
71°
Step-by-step explanation:
3x° + (x - 11)° + (2x - 55)° = 360°
3x + x - 11 + 2x - 55 = 360°
6x - 66 = 360°
6x = 360° + 66°
6x = 426°
x = 71°
