Answer:
(x+5) metres
Step-by-step explanation:
correct question
<em>The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?</em>
<em></em>
Area of the rectangle = Length * width
Factorize the area
A(x) = x^2+8x+15
A(x) = x^2+3x+5x+15
A(x) = x(x+3) + 5(x+3)
A(x) = (x+3)(x+5)
Since the width is x+3, the length of the rectangle will be (x+5) metres

3/5 -> 12/20
1/20 -> 1/20
The set A satisfying the given inequality is A = (-, -10].
<h3>What are some properties of an inequality relation? </h3>
Following are some facts which are true for an inequality relation:
- Equal numbers can be added or subtracted from both sides of an inequality without affecting the inequality sign.
- The Inequality sign is unchanged if both sides are multiplied or divided by a positive number, but when multiplied or divided by a negative number the inequality sign is reversed.
Since y ∈ B, -2 ≤ y ≤ 7. So,
The set {-x | inequality (1) holds ∀ y ∈ B} is [10, ) i.e.
10 ≤ -x ≤ .
Multiplying -1 throughout gives
-10 ≥ x ≥ -.
x, thus, lies in the range A = (-, -10}.
