Answer:
I can't currently fully answer, hoping someone can come along and help-
Step-by-step explanation:
separate the shape into 3 triangles and 1 rectangle and then add all the areas together
area of a triangle is 1/2 base times height and area of a rectangle is length multiplied by width
It’s a right triangle because it has a 90 degree angle
Honestly, the most intelligent solution would be to light the candle first, since it has a longer duration and then I can light the lamp, and then I can light the newspaper. Then, I will use the newspaper to light the fire.
Answer:
Step-by-step explanation:
Let the rate of commission is x%.
<u>Total earning is:</u>
- 7500 + 120000*x/100 = 13500
- 1200x = 13500 - 7500
- 1200x = 6000
- x = 6000/1200
- x = 5
Answer:
The area of square in terms of x = 16x² -24x + 9
Step-by-step explanation:
It is stated in the question that the length of a square = 4x - 3
Formula to find the area of the square is
<h2 /><h2>Area = length²</h2><h2 />
Area = ( 4x - 3 )²
<em>by using ( a - b )² = a² + b² - 2ab</em>
here a = 4x and b = -3
So,
(4x)² + (-3)² - 2(4x)(3)
16x² + 9 - 2(12x)
16x² + 9 - 24x
16x² -24x + 9
The area of square in terms of x = 16x² -24x + 9
