Answer:
height = 4.8 cm
area = 120 cm²
perimeter = 62 cm
Step-by-step explanation:
<u>**Please refer to the attached diagram when following the step-by-step**</u>
First, find m∠C (green angle on diagram) by using the cosine rule:
Therefore, the interior angle of the right triangle at point C (blue angle on diagram) is:
Now use the Sine Rule (for finding sides) to determine height (h):
So the height = 4.8 cm
Now we have determined the height, we can calculate the area by using the area of a parallelogram formula:
Area of a parallelogram = base x perpendicular height
⇒ area = 25 x 4.8 = 120 cm²
Parallelogram is a four-sided shape made up of two pairs of straight parallel lines that are equal in length.
Perimeter = sum of the sides
⇒ perimeter = 6 + 6 + 25 + 25 = 62 cm
If there is suppose to be a negative sign.
3x -1(2x + 4x - 6)
Distribute the -1 to all terms within the parenthesis
-1(2x + 4x - 6) = -2x - 4x + 6
3x - 2x - 4x + 6
Simplify. Combine like terms
(3x - 2x - 4x) + 6
-3x + 6
-3x + 6 is your answer
hope this helps
Answer:
The reason why this may be happening is because the expenses may be higher than the amount of revenue that the business is making, the cost of rent, paying the employees and running the business may be higher than the revenue that is being made. The inflows may be higher than the outflows, in which case the profit is lower than the loss and may be the reason why the owner is having trouble keeping the business running.
I believe the answer is B
Answer:
(-3,3)
Step-by-step explanation:
Using elimination:
Multiply the first equation by 8 and the second by 5 which equals
40x+56y=48
-40-60y=-60
Now you add them together
40x+(-40x)=0 so that crosses out
56y+(-60y)= -4y
48+(-60)=-12
You now have -4y=-12
Divide by -4
y=3
Now plug in y to any of the equations
5x+7(3)=6
5x+21=6
Subtract 21 from both sides
5x=-15
Divide by 5
x=-3
Your final solution is (-3,3)
