If the blue center is 24 inches long and 40 inches wide. The area of the green border is: 960 in².
<h3>How to find the area?</h3>
Using this formula to find the area
Area = l × w
Where:
L =length = 24 inches
W = Width = 40 inches
Let plug in the formula
Area = 24 inches × 40 inches
Area = 960 in²
Therefore the area is 960 in².

Answer:
B. 38°
Step-by-step explanation:
The angles of a triangle add up to 180.
So, 62 + 80 + b will add up to 180.
First, we add 62 =80, which gives us 142.
The we subtract 142 from 180, which gives us 38.
The slope is rise over run

Hi there Brook!
First, you need to find the slope of this linear line, because if two lines are parallel they have the same exact slope.
2y + 10x = -36 <-- Subtract 10x on both sides
2y = -10x - 36 <-- Divide everything by 2
y = -5x - 18 <-- Your re-organized linear equation, with the slope of -5.
Now that you know the slope is -5, but not the y-intercept since the line is different, look at the coordinate you have. Since you know that an input of -1 makes an output of 4, you can create an equation:
4 = -5(-1) + b <-- Four equals the slope times the input, plus the y-intercept
4 = 5 + b
b = -1, since 5 + (-1) = 4.
So, now your final equation is y = -5x -1
Answer:
<40, 28, 72>
Step-by-step explanation:
y and z are the following vectors:
y = <2, 6, 8>
z = <7, -2, 6>
To find 6y + 4z, first compute the scalar multiplications:
6y = <6*2, 6*6, 6*8> = <12, 36, 48>
4z = <4*7, 4*-2, 4*6> = <28, -8, 24>
Then, add the obtained vectors, as follows:
6y + 4z = <12 + 28, 36 - 8, 48 + 24> = <40, 28, 72>
