L = W + 12
P = 7W = 2L + 2W
7W = 2W + 24 + 2W
3W = 24
W = 8
L = 20
Answer: 7/10 ÷ 3/8 = 1 13/15
Step-by-step explanation:
Its 1 whole and 13/15
The dimensions of the outer rectangle are
Width = x + 6x + x = 8x
Length = x + 9x + x = 11x
The area is
A1 = (8x)*(11x) = 88x²
The dimensions of the inner rectangle are
Width = 6x
Length = 9x
The area is
A2 = (6x)*(9x) = 54x²
The shaded area is the difference between the outer and inner rectangles.
Therefore the shaded area is
A = A1 - A2 = 88x² - 54x² = 34x²
Answer: 34x²
The value of expression without the negative exponent is,
⇒ 2/x⁴
What is Rule of exponent?
The rule of exponent is defined as;
aⁿ = 1/a⁻ⁿ
Now, The expression is given as;
2x⁻⁴
It can be rewrite as;
2x⁻⁴ = 2 / x⁴
Hence, The value of expression without the negative exponent is,
⇒ 2/x⁴
