Answer:
£45
Step-by-step explanation:
Say the original price is x. When we take 20% off, that's basically multiplying x by 20% and then subtracting that product from the original price, which is x:
x - 20% * x = 80% * x = 0.8x
Now, this equals £36, so we just set them equal:
0.8x = 36
Dividing by 0.8 from both sides, we get:
x = £45
Thus, the answer is £45.
It’s 18x because 36 and 54 are both divisible by 18, and 18 can be divisible by 18 (making 1), resulting in 18 being the most common number between the numbers, whereas the ‘x’ is common between all 3 numbers and since the least amount of x is 1, the answer is just x without an exponent
We Know, perimeter of square = 4a
Area of square = a²
Now, A.T.Q,
8*4a = a²
32a = a²
a²/a = 32
a = 32
So, side should be 32
Hope this helps!
The area of figure ABCDEF can be computed as the sum of the areas of trapezoid ACDF and triangle ABC, less the area of trangle DEF.
trapezoid ACDF area = (1/2)(AC +DF)·(CD) = (1/2)(8+5)(6) = 39
triangle ABC area = (1/2)(AC)(2) = 8
triangle DEF area = (1/2)(DF)(2) = 5
Area of ABCDEF = (ACDF area) + (ABC area) - (DEF area) = 39 +8 -5 = 42
The actual area of ABCDEF is 42 square units.
