Answer:
X = (J+M)/K
Step-by-step explanation:
Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).
KX = J +M . . . . . . M added to the given equation
X = (J + M)/K . . . . the result of that is then divided by K
___
Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."
Then your solution looks like
X = K⁻¹·(J + M)
The area of the arrow given in the figure is 610 square cm
<h3>Area of composite figure</h3>
The given figure is made up of rectangle and triangle. The area is expressed as:
Area = Area of rectangle + area of triangle
Substitute the given parameters
Area of the arrow = (15*20) + 0.5(31 * 20)
Area of the arrow = 300 + 310
Area of the arrow = 610 square cm
Hence the area of the arrow given in the figure is 610 square cm

Answer:
1.
cm
2. 318.198 ft^2.
Step-by-step explanation:
Hmm. Very stuck. We'll just take it slow. :)
For the first one, we'll just square the bottom of the parallelogram, because
it's a square. The answer is above.
The second is a bit more complicated. The formula for the area of a parallelogram is (base) x (height)= A(area), but that will be of no use until we know the height (the dashed line on the left).
So, do let's go about finding the height with a 45-45-90 triangle.
The way these work is that the two short sides are equal to x, and the longer one is
. So, in essence,
.
15/
=10.61
Both of the other two sides (one being the height) are 10.61 ft long.
Multiply that by 30:
30 x 10.61= and you get 318.198 ft^2.
